Scientific problems are computationally intensive and a lot of time is acquired to get the outcomes by utilizing computer with one processing element. High Performance Computing (HPC) describes utilization of many processors executes a computationally intensive task in parallel, which reduces the processing time. At present, one of the leading and fastest parallel computers is supercomputer contains the processing elements hundreds to thousands. A lot of effort and cost is needed to build very fast and dedicated supercomputers. Alternative is to build low cost HPC clusters using inexpensive hardware. In this paper, we implemented tested, compared and analyzed the processing ability of 3 different x86-based and ARM-based low cost HPC clusters in terms of execution time and speedups. Finally concluded that in spite of the performance, clusters build with ARM-based single board computers are functional and handy for academic point of view due to its low-price and value to the restrictions of electricity.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114074734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid the above under-determined problems, data associated iterative channel estimation is effective, where tentatively detected data (soft symbols) based on iterative detection is utilized as additional pilot sequences. However, the detection capability of PDA is severely degraded by modeling errors which are caused by decision errors included in soft value and the non-orthogonality of additional pilot sequences. For mitigating the negative impacts of the modeling errors, a novel covariance matrix for MU detection (MUD) is designed according to the incompleteness of tentative pilots. Finally, we verify the validity of the proposed method in terms of the suppression of the bit error rate (BER) floor.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127844631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To adopt NIT-KF with NNC, we address the adjustment of biased Kalman gain through efficient parameter estimation. We introduce an effective noise spectrum tracking method based on decision directed approach (DDA) controlled through a posteriori SNR and speech activity detector (SAD). With the estimated noise spectrum, the spectral over subtraction (SOS) algorithm is employed to the noisy speech; this gives a pre-filtered speech (PFS). The noise variance and LPCs are computed from the estimated noise and PFS, respectively. These are applied to NIT-KF to produce the enhanced speech. It is shown that the adjusted Kalman gain in NIT-KF is effective in minimizing the additive noise effect to an acceptable level. Extensive simulation results reveal that the proposed method outperforms other benchmark methods.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129066421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main idea is to use a metallic part of2U CubeSat's surface at distance of 12 mm below the antenna as a reflector to redirect the back radiation forward. This leads to a substantial suppression of back lobe radiation and hence significant increase of the antenna total gain. The simulation results show that the antenna achieves a superior gain of 9.39 dB, wide b-10 dB bandwidth of 370 MHz (2.53-2.90 GHz) and return loss of −22 dB at a resonant frequency of 2.7 GHz.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126632272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the rapid growth of wireless communications, modulation classification has become a critical factor for efficient and high-performing receiver designs. Automatic modulation classification impacts critical civilian and military applications. In civilian applications, various forms of quaternary and 16-point modulations (QASK, QFSK, QPSK, 16-QAM, etc.) are deployed. For this group of modulations, the two dominant AMC approaches proposed in the literature are Likelihood- (LB) and Feature-based (FB) classification. Feature-based approaches focus on five main properties: Signal Spectral-based Features, Wavelet Transform-based Features, High-order Statistics-based (HoS) Features, Cyclostationary Analysis-based Features and Graph-based Cyclic-Spectrum Analysis Features, all of which are employed to extract initial information for the classifier. In this work, we analyze the performance of automatic modulation classification applied for civilian modulations with various features under practical scenarios.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128040454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of these devices are powered by battery as their sole energy source, where energy-efficiency is of utmost importance to prolong the lifespan of these devices over next generation networks. This paper proposes an energy-efficient framework for adaptively controlling the transmit power and data rate of the IoT device in order to minimize the energy-consumption in 5G networks. Many of the envisioned IoT applications are latency insensitive such as utility metering, environmental monitoring, and logistic tracking. We prove that by using a simple retransmission scheme we can significantly enhance the energy-efficiency while preserving the rate of successful message delivery. The framework is tested using real measurements of LoRa technology and compared against other legacy modulation schemes currently implemented in IoT systems. Results show that significant energy saving can be achieved by applying this proposed framework.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126575282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For statistical significance Pearson's Correlation method is used. The connectivity was estimated using coherence on single trial EEG data from a visual oddball paradigm. The pairwise coherence coefficient of all 19 electrodes was grouped into a 19×19 connectivity matrix for further analysis. The data of two subj ects was averaged to perform group comparisons between the two oddball cases. Absolute thresholding method was applied on the matrices to form undirected graphs. It is found that the connectivity matrix of TR is significantly different from NTR. Firstly the connectivity in TR case has higher weight than NTR case. Secondly TR case has higher network density value than NTR case. Lastly Frontal-Temporal (F - T) and Occipital-Temporal (O-T) links which are related to the triggering of P300 were observed in TR case but not in NTR case.

The AF-DOOK system is the advance of the conventional framed-DOOK system by extending the synchronization signal from 1-bit to 2-bits. The AF-DOOK system has a frame error detection method which the conventional framed-DOOK system does not have. In this paper, the frame error detection performance by 2-bits synchronization signal of the AF-DOOK system is investigated. The theoretical formulas to assess frame error detection performance are derived and evaluated; the frame error detection probability, the frame error undetected probability, and frame error misdetection probability. Consequently, it is indicated that the frame error detection method of the proposed AF-DOOK system is practically effective under the optical-wireless channel with scintillation and background noise.","PeriodicalId":179948,"journal":{"name":"2018 12th International Conference on Signal Processing and Communication Systems (ICSPCS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132242533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
