To further satisfy the ever increasing demand for data rates, 5G NR can also be operated on the unlicensed mmWave bands. In this direction, various channel access schemes that consider Listen Before Talk (LBT) and Listen Before Receive (LBR) have been proposed in the literature. However, a thorough comparison of these schemes for fair coexistence with 60 GHz WiFi, also termed as WiGig, in different scenarios is needed. Hence, in this paper, we compare the performance of a combination of omni-directional and directional channel access schemes with LBTILBR/both in the presence of a realistic mmWave array antenna pattern, 3GPP mmWave Indoor path loss model, and fixed backoff mechanism for collision avoidance. Through extensive simulations, we show that the directional LBT combined with directional LBR and omni-directional LBT schemes perform better than other schemes in terms of sum rate, mean rate, and minimum rate in the system. Moreover, directional LBT performs better in terms of number of channel access and proportional fairness in the system as compared to other channel access schemes.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120987493","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}

We consider a three-node half-duplex relaying system with two source nodes and a relay node. To address the needs of present day energy constraint battery enabled relay nodes, we employ simultaneous wireless information and power transfer (SWIPT) for energy harvesting (EH) from ambient resources through time-switching protocol. Further, since a low-cost and low-complexity relay node has a non-linear power amplifier, we consider the impact of the same in the analysis. Framework, for outage probability of SWIPT enabled two-way relay system with non-linear amplifier is presented. Additionally, throughput analysis is performed and affect of non-linearity, EH and relay power over the system is analyzed. Accuracy of the derived expressions and impact of non-linear power amplifier over the SWIPT system are verified through the Monte-Carlo simulations.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127617932","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}

MSMC is a language independent speech mode classification model that could detect the mode of speech spoken in any language. Here, we considered data of three broad speech modes: conversation, extempore, and read from three Indian languages, namely, Telugu, Bengali, and Odia. The vocal tract information is captured using Mel-frequency cepstral coefficients. The pitch contour processed at supra-segmental level represents the excitation source information. The MSMC model is developed using multilayer perceptron. Experimental results show that the vocal tract features provide better overall identification accuracy, compared to excitation source information. Further, an improvement in overall accuracy is achieved by combining the scores obtained by two separate MSMC model based on excitation source and vocal tract features. The results generated using a combined score, outperform the model developed using standard vocal tract feature.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130743258","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}

However, the conventional VQA model uses video as a two-dimensional image sequence and extracts the features on a frame to frame basis; which completely neglects temporal nature of the video data and the corresponding distortion content as well. In this work, we come up with a novel no-reference VQA model that describes and exploits the inter sub-band statistics of the three-dimensional discrete wavelet transform (3-D DWT) coefficients of video blocks. First, the 3-D DWT transform decomposes the video block of selected size into eight 3-D DWT sub-bands. Then we propose various novel statistical features using the sub-band coefficients. Inter sub-band statistics depicts the spread of the various frequency components and correlation between them. 3-D DWT features automatically take care of the temporal distortions along with spatial distortions and subsequently the support vector regression (SVR) model estimates them to predict the visual quality score of distorted videos. Experimental results on LIVE database demonstrate the superiority of the proposed VQA model over the other state-of-the-art methods.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130080940","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}

Utilization of directional mmWave for Device to Device (D2D) communication systems provides low powered, high data rate transmission with manageable interference. In this paper, the rate and outage probability for mmWave integrated D2D communication system under Nakagami-m fading channel are derived. The performance of the model is analyzed by obtaining the closed-form expressions for the outage probability of a D2D user, wherein multiple cellular or D2D users are interfering with a mmWave integrated D2D transmission. The impact of various system parameters such as sectored beamforming gain probabilities and distance from interfering nodes on D2D outage probability are also investigated. Results show that the D2D outage probability decreases with an increase in main lobe gain, whereas increases with an increase in side lobe gain.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133891093","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 proposed algorithm is based on the combination of a mechanism for proportionate gain control, and a mixed $l_{2},0$ norm regularization, and outperforms the existing class of block proportionate sparsity-induced algorithms. The performance analysis of the proposed algorithm is then carried out, providing limits to the mean deviation from the original system. We also propose an improved proportionate type block sparse adaptive filtering algorithm with modified gain control mechanism. This one is more robust to the varying degrees of sparsity in the system to be identified than the former.

Typical Brain Computer Interface systems comprise of signal acquisition, feature extraction and classification modules. The focus in this paper is to experimentally evaluate various feature extraction and classification modules to comparatively determine the best performing feature-model(FM) pair. Few popular FM variants are implemented to classify units from coSpeech-EEG data collected during speech audition, imagination and production. Performance variations across sessions and subjects are also studied to analyse scalability and robustness of the various FM pairs. Simultaneous diagonalization of multiclass common spatial patterns obtained on EEG data coupled with a Gaussian mixture model based Hidden Markov Model proves to be the best FM pair for the task at hand rendering an average accuracy much higher than chance across 30 subjects in a multi-unit classification problem.","PeriodicalId":183772,"journal":{"name":"2020 National Conference on Communications (NCC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122062650","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 absorption band lies from 5.04 to 11.38 GHz for both the states, covering C and X bands in the spectrum, while the OFF-state transmission band is appearing at 2.82 GHz in the rasorber.
