In this paper, the symmetry of the mode transmission matrices of AOAMM systems is proven. According to this feature, a modified algorithm that performs bidirectional interference cancellations for AOAMM systems is proposed. The results show that the proposed algorithm outperforms the standard minimum mean squared error (MMSE) with ordered successive interference cancellation (OSIC) algorithm and approaches to the bit error rate of the MMSE-based sorted QR decomposition with $M$-algorithm, when the topological charge intervals are small in the region of low to moderate signal-to-noise ratios. The proposed algorithm makes the AOAMM systems available in practice.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129874108","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}

Thus, the phase and amplitude of phased array antenna should be measured and calibrated. An measurement method of phased array antenna based on self-calibration RF channel is presented in this paper. First of all, the initial amplitude-phase is measured by self-calibration RF channel. Secondly, the modified value related to self-calibration RF channel is achieved by use of Mid-field receiving power calculation method. Finally, the actual amplitude and phase weighting factor of phased array antenna is obtained, based on calibration of the initial amplitude-phase with the modified value. The comparison of planar near-field measured results show that the proposed method is feasible and efficient.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132327048","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}

Its total throughput changes with the channel selection of terminals, because two channels have different attraction probabilities under the condition that the total packet arrival rate remains constant. We establish a group of differential equations for each channel’s network-adjusted arrival rate, and obtain the function relationship of total throughput with the total arrival rate. The influence of the different allocation ratio about jamming resources on each channel is analyzed under the condition that the jamming resources are kept constant. The optimal allocation ratio of jamming resources is obtained, and the total throughput is minimized for this network. The above theoretic analysis is verified by simulations. It not only puts forward a new way for effective jamming on dual-channel ALOHA network with long time delay, but also provides an important reference for the dynamic characteristics research for such networks.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"56 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126236325","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}

This paper presents Infrastructure-assisted Markov Prediction Routing Protocol (IAMPR) for urban VANET scenarios. IAMPR formulates corresponding routing algorithms for vehicles and RSUs in order to exploit the available heterogeneous network efficiently. Store-and-forward buffering, Markov chains predictor and duplicate transmission techniques are also adopted in the protocol aiming at local minimum problem cause by greedy forwarding strategy. To better evaluate the performance of IAMPR, we complete simulation in NS-3 simulator under a real world topology urban scenario. Simulation results show that our proposed protocol outperforms Greedy V2I2V and GPSR in terms of packet delivery ratio and end to end delay under varying vehicles densities and speeds.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"238 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114211405","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}

In our scheme, the low-frequency band is allocated to a GFDM signal to achieve a low peak-to-average power ratio (PAPR), while the high-frequency band is filled with an OFDM signal that is robust to frequency-domain variations. By this means, the PAPR of the whole signal can be reduced and the high-frequency fading effects induced by the electronic components can be mitigated, leading to an improved system performance. Simulation results show that our proposed GFDM-OFDM format outperforms OFDM and GFDM formats in terms of optical receiver sensitivity for both the back-to-back (BTB) and 10-km transmissions. The GFDM-OFDM signal achieves receiver sensitivity improvements of approximately 3.0 dB and 1.6 dB, compared to the OFDM and GFDM signals, respectively.","PeriodicalId":243383,"journal":{"name":"2018 10th International Conference on Communication Software and Networks (ICCSN)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123173057","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}
