Recently, MIMO Two-way Multi-hop Network (MTMN) has been introduced as a communication scheme to improve channel capacity of relay networks. Moreover, the strategy of Power Adaptation (PA) has been proposed for MTMN to adjust the Signal-to-Interference plus Noise Ratio (SINR) to achieve the highest performance. However, the studies of MTMN has been based on Rayleigh fading channel model which may be far from the reality since all links in the network are not in the same condition, especially when shadowing is dominant. Moreover, the realization of optimum placements in MTMN for relays in the real shadowing environment is still a left-behind issue. Therefore, this paper aims to investigate the optimum relay placements of MTMN by conducting 3D ray-tracing simulation of propagation channel in a real shadowing environment. Based on the results, the optimum relay placements of MTMN without PA are where relay links do not suffer from shadowing effect. On the contrary, the results show that the optimum placements for MTMN with PA case is different since PA can more efficiently reduce the interference at these locations. In addition, this paper proposed a methodology to estimate the optimum locations for MTMN with PA by using the knowledge of node-to-node signal strength which can be simply obtained in the real environment.","PeriodicalId":333610,"journal":{"name":"2012 IEEE 75th Vehicular Technology Conference (VTC Spring)","volume":"2003 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125781472","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}

Single-carrier (SC) MIMO block transmission using frequency-domain signal detection such as the frequency-domain linear detection based on the minimum mean square error criterion (MMSED) can improve the HARQ throughput performance over the frequency-selective fading channel. However, the performance improvement is limited due to not only an inter-antenna interference (IAI) but also an inter-symbol interference (ISI) resulting from a severe frequency-selective fading. In this paper, we propose to jointly use a training sequence (TS) aided SC block transmission and a near maximum likelihood (ML) block detection using QR decomposition and M-algorithm (QRM-MLBD) for SC-MIMO HARQ. It is shown, by computer simulation, that SC-MIMO using TS aided QRM-MLBD significantly improves the HARQ throughput performance compared to an often used cyclic prefix (CP) inserted SC-MIMO while significantly reducing the computational complexity. It is also shown that proposed TS aided QRM-MLBD achieves a significantly higher throughput than the MMSED particularly when higher level modulation is used.","PeriodicalId":333610,"journal":{"name":"2012 IEEE 75th Vehicular Technology Conference (VTC Spring)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126603313","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 relays will bring extra interference to macro cell and the popular solution is to allocate different bandwidth for relays and base stations. In this paper, we use proportional fairness mode to formulate this frequency resource allocation optimization problem and presented a new adaptive method (both centralized and distributed algorithm) with interference coordination based on dynamic traffic load for cell-edge relay deployment. This resource allocation scheme with both intra and inter cell interference coordination (ICIC) can greatly improve the spectrum efficiency compared with conventional static ICIC schemes, in which the cell- edge bandwidth is equally allocated among the neighboring base stations or relays. Based on our performance evaluation, the proposed method can flexibly adapt the case when the traffic load distribution is non-uniformed or mobility occurs frequently, which accordingly exploit the cellular capacity with the experience enhancement of the cell-edge users.","PeriodicalId":333610,"journal":{"name":"2012 IEEE 75th Vehicular Technology Conference (VTC Spring)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126753957","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 performance of radar sensors in practical setups depends on many factors, such as sensor specifications, choice of locations, height and orientations of sensor installation. Currently, most of these choices are made by a \"rule of thumb\". In many cases, trial and error changes of settings are required and several rounds of on-site measurements and adjustments are incurred, which are both inefficient and costly. To overcome these problems, this paper reports a 3D virtual radar system that can accurately predict and evaluate the performance of actual radar sensors using a standard computer. The proposed system builds upon a 3D virtual model of real world. It allows users to freely enter specifications for radar sensors and the underlying algorithm can efficient calculate and represent graphically in the 3D model by the coverage area of the chose radar sensors at the specified location in the virtual world. Comparison with experimental data obtained using hardware testbeds shows the result obtained by the virtual radar system is accurate.","PeriodicalId":333610,"journal":{"name":"2012 IEEE 75th Vehicular Technology Conference (VTC Spring)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115549470","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}
