For a long time, researchers have made great efforts to efficiently utilize the limited energy storage of sensors. Recently, it was shown that external energy resources can be harvested by the sensors in order to increase their lifetime. This paper elaborates on the role of recharging in energy efficiency for wireless sensor networks. Particularly, several energy efficiency scenarios with recharging are discussed. The new facets brought by recharging are highlighted. A representative example is provided to show the advantage of recharging in sensor networks. This paper is dedicated to serve as a tutorial which calls for more attention to the exciting research topic-recharging for wireless sensor networks.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134067127","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 coverage range of relay station is determined by its transmit power and level of handover between relay station and its base station. This coverage range directly influences to handover performance. If number of handover increases, the expense of signaling overheads and capacity deficiency will be increased. In this paper, the investigation into number of handover related to coverage range of relay station is presented. In addition, various handover scenarios in cellular networks are also examined. The results indicate that the tradeoff between number of handover scenarios and coverage range depends on type of handover scenarios.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115535776","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 this paper, we propose a novel successive interference cancellation (SIC) detector for multiuser detection in multiuser Multiple Input Multiple Output (MIMO) SC-FDMA system with co-channel interference (CCI). Compared to conventional SIC receiver, the proposed scheme can overcome the error propagation problem in the interference cancellation process via soft-decision output combined with channel decoder. And we also study the impact of the channel estimate error on the receiver and investigated it via simulation. Simulation results show that the proposed algorithm is significantly superior to the conventional frequency domain linear equalization based receiver in terms of bit error rate (BER) performance even the channel statement information is imperfect at the receiver.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116049373","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}

Specially, under the constraint that the interference power introduced to primary users (PUs) is kept under a tolerable threshold, we investigate the system throughput maximization problem during the cognitive relay transmission. In order to make the formulated problem feasible to solve, Maclaurin expansions are employed as substitutions. Moreover, based on convex optimization theory, an iterative power allocation algorithm repeated between the powers of secondary source node and relay node is developed to obtain the optimal solution. Corroborant numerical examples are provided to illustrate the quick convergence behavior of the proposed algorithm and the superiority of applying cooperative relay in cognitive radio networks is also presented.","PeriodicalId":448094,"journal":{"name":"2010 International Conference on Wireless Communications & Signal Processing (WCSP)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115012761","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}

Firstly, noisy speech signals are transformed into Gammatone spectrum by using cochlear filtering; then, unreliable spectral components are reconstructed given an incomplete set of reliable ones; finally, speaker features with auditory model are extracted from reconstructed Gammatone spectral data.
