The transmitter preprocessing (TP) is invoked by singular value decomposition (SVD) which exploits the channel state information (CSI) of all the users at the base station and only the individual user's CSI at the mobile station (MS). Specifically, in this correspondence, we investigate the effects of two types of delay spread distributions pertaining to Long Term Evolution (LTE) pedestrian and typical urban on MUTP assisted MIMO system. In a multi-cell setting, co-channel interference (CCI) can severely degrade the system performance and further, frequency-selectivity of the channels can result in irreducible bit error rate (BER). It is demonstrated through simulation that, MUTP completely removes CCI and also outperforms classical zero-forcing multiuser detection (ZF-MUD).","PeriodicalId":320235,"journal":{"name":"2012 International Conference on Communication and Signal Processing","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129232657","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}

RoF networks is considered as a potential solution for increasing capacity and mobility as well as decreasing costs in the access network. RoF can also be called as Fiber radio networks or Hybrid optical-wireless networks. The concept of RoF means to transport information over optical fiber by modulating the light with the radio signal. This modulation can be done directly with the radio signal or at an intermediate frequency. RoF technique has the potentiality to be the backbone of the wireless access network. Such architecture can give several advantages, such as reduced complexity at the antenna site, radio carriers can be allocated dynamically to the different antenna sites, transparency and scalability. The Fiber-Radio networks transmits data from Central office (CO) to Base station (BS) as optical signal and Base station (BS) to Mobile station (MS) as wireless signal. Due to the signal degradation mechanisms present both in fiber and wireless transmissions, the radio signals transmitted using RoF technology undergoes degradation in their quality, which in turn reduces the overall performance of the RoF system. This paper aims to analyze and evaluate the performance of RoF System, by considering Millimeter wave and UWB signal transmission for WLAN. Special attention is made on chirp effect caused by Mach Zehender (MZ) external optical modulator.","PeriodicalId":320235,"journal":{"name":"2012 International Conference on Communication and Signal Processing","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126549116","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 particular, the CSI is estimated with a known channel estimation technique, and the phases and magnitudes of the CSI are vector quantized and fed back to the transmitter via a fading feedback channel. This vector quantized CSI which is also corrupted by noise is recovered with the aid of a minimum mean square error (MMSE) based hard detector. The recovered CSI is then exploited to formulate the preprocessing matrix which is based on creating an orthogonal subspace to the interfering subspace. Our simulations show that the impact of codebook size and quantization errors play a dominant role in determining the performance of the considered DL system in terms of the achievable symbol error rate (SER).","PeriodicalId":320235,"journal":{"name":"2012 International Conference on Communication and Signal Processing","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129638153","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}

It is widely believed that a well-modularized software system is easier to develop and maintain. Typically, a good module structure is regarded as one that has a high degree of cohesion and a low degree of coupling. Automated techniques are used for suggesting software clustering, delimiting boundaries between modules that maximize cohesion while minimizing coupling. Implications of software modularization are considered on many software engineering concerns. Badly modularized software is widely regarded as a source of problems for comprehension, increasing the time for ongoing maintenance and testing. Cohesion and coupling are used to assess module structure. Software module clustering is the problem of automatically organizing software units into modules to improve program structure. There has been a great deal of recent interest in search-based formulations of this problem in which module boundaries are identified by automated search, guided by a fitness function that captures the twin objectives of high cohesion and low coupling in a single-objective fitness function. The system uses multi objective model for module clustering process. The multi-objective approach produces significantly better solutions than the single-objective approach. The proposed system is designed to improve the module clustering process. Multi objective functions with dynamic criteria selection model is used in the system. Module size and communication bandwidth features are used in the objective functions. Feature location is also used in the multi objective functions.","PeriodicalId":320235,"journal":{"name":"2012 International Conference on Communication and Signal Processing","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123671945","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}
