Since their seminal work, several schemes have been proposed to characterize optimal memory rate tradeoff to the caching problems. In this paper, we consider the (4, 5) cache network where the server has four files, each of size F bits, and five users are connected to the server through a common shared link. We consider the demands where each file in the server is requested by at least one user. For this cache network, we derive an improved lower bound for the small cache region, where the cache size in the range of $displaystyle frac{1}{5}F$ bits to $displaystyle frac{4}{5}F$ bits. We also introduce a new caching scheme to achieve the memory rate pair $left(displaystyle frac{61}{20},frac{1}{4}right)$. We then derive a new lower bound for the cache region where cache size in the range of $displaystyle frac{61}{20}F$ bits to $displaystyle frac{16}{5}F$ bits to prove the optimality of the proposed scheme.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124062742","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}

A hybrid combining based low complexity fusion rule is derived at the fusion center (FC) that also incorporates the local probabilities of detection and false alarm of the individual sensor nodes, thus making it suitable for practical scenarios. Closed-form expressions for the probabilities of detection and false alarm are evaluated to characterize the system performance. Moreover, a deflection coefficient maximization based framework is also developed to determine the signaling matrix that further improves the detection performance of the proposed scheme. Finally, simulation results are presented to demonstrate the performance of the proposed detector and to corroborate the analytical results.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127600669","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 SEUVIPT system consists of EUV photo Light Emitting Diode (LED) at the transmitter and EUV photo detector at the receiver in a high vacuum atmospheric EUV channel. The energy harvesting optimization problem has been formulated for the proposed model using information rate and signal to noise ratio. Power splitting protocol is used for energy harvesting and information transmission. The energy harvesting maximization problem is non-convex. It is converted into convex and an expression for the optimal energy harvesting is derived for the proposed model.

The proposed approach is different and complementary to the conventional target tracking algorithms that are widely deployed in the back-end of radar systems. The received signals are modelled as time-varying low-rank matrices and passed through an adaptive singular value thresholding (ASVT) block, resulting in the elimination of noise returns early in the processing chain. When all the antenna elements are not being used and the received signal is only partially observed, the ASVT block imputes the missing entries. Front-end processing results in cleaner signals for the back-end, culminating in fewer range and Doppler bins, increased probability of detection, reduced false alarm rate, and ultimately, improved target tracking performance. Detailed simulation of the radar chain reveal the significant improvements afforded by the proposed algorithm.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131015824","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}

Non-orthogonal multiple access (NOMA) is envisioned to address this challenge by circumventing the need for spectrum allocation (as in orthogonal multiple access schemes) which limits the number of users. We formulate an analytical model to evaluate the total system capacity achievable by using NOMA in a multiple-input-multiple-output (MIMO) VLC system. We analyze the total capacity of a NOMA based $2 times 2$ MIMO-VLC system employing two different power allocation schemes, namely, gain ratio power allocation (GRPA) and normalized gain power allocation (NGDPA), for power domain superposition coding at the transmitter. We evaluate and compare the performance of these two schemes for various system parameters like system coverage, user location and number of users. The results and analyses presented herein provide critical insights into the modelling of NOMA based MIMO-VLC systems.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130394911","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 fulfill this requirement, a variety of Adaptive Bit-Rate Streaming methods for Video-on-Demand applications are employed. However, the use of multi-pass encoding in the aforementioned methods renders them obsolete when it comes to real-time video streaming due to latency restrictions. In this work, we bypass the conventional multiple-encoding used in Video-on-Demand applications and present a novel machinelearning-based approach that estimates the optimal video resolution for a given content at a particular bit-rate for ultra low latency applications. A new feature that captures temporal as well as spatial correlation in video sequence has been used to train the Deep Neural Network (DNN) model. A python-based testbed is designed to evaluate the proposed scheme. Experiment results corroborate the viability and effectiveness of the proposed method for real-time mobile video streaming applications.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133485418","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}

Using tools from stochastic geometry, we provide an analytical framework to derive the SINR and rate coverage of a typical receiver located at the origin.

We show that rate coverage is affected by the size of the connectivity region and there exists an optimal size of connectivity region that maximizes the rate coverage.","PeriodicalId":208527,"journal":{"name":"2020 International Conference on Signal Processing and Communications (SPCOM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130224591","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}
