The similarity of two or more steering vectors corresponding to widely separated directions in the array manifold causes ambiguity in the DOA estimation. Recently, half-space ambiguity resolution has been done by optimizing the structure of the AWPC, based on Cramer-Rao bound. This paper further proposes a novel method for resolving whole-space ambiguity in the DOA estimation by using a uniform circular array (UCA) with multiple optimal AWPC sensors. The optimal number of AWPC sensors in moderate-size UCAs is also obtained by numerical optimization.","PeriodicalId":282211,"journal":{"name":"The 2012 International Conference on Advanced Technologies for Communications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123458805","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}

Unfortunately, OAC codes suffer from transmitting “zero-symbol” on all transmit antenna. The “zero-symbol” in the design results in high peak-to-average power ratio (PAPR) and also imposes a severe constraint on hardware implementation of the code when turning off some of the transmitting antennas whenever a “zero-symbol” is transmitted. In this paper, we propose a new space-time block code (STBC) for linear receivers. The proposed STBC achieves all desirable properties of OAC codes as full diversity, high rate and group orthogonality. In addition, transmitting “zero-symbol” only occurs on half of transmit antenna instead of all transmit antenna as for OAC code. As a result, the proposed STBCs not only have lower PAPR, but also easier implementation than OAC codes. Moreover, simulation results also show that our codes outperform OAC codes under peak power constraint.","PeriodicalId":282211,"journal":{"name":"The 2012 International Conference on Advanced Technologies for Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128971693","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, one of the main challenging issues for NoC designers is that the network performance should be rapidly and early pre-proved for target applications. In this paper, we present a NoC simulation and evaluation platform allowing designers to simulate and evaluate the NoC performance with different network configuration parameters. The proposed platform has been implemented in SystemC to be easily modified in order to adapt different simulation strategies and save the simulation time. With this platform, designers can deal with: (i) configuring the network topology, flow control mechanism and routing algorithm; (ii) configuring various regular and application specific traffic patterns; and (iii) simulating and analyzing the network performance with the assigned traffic patterns in terms of latency and throughput. Obtained results with a 4 × 4 2D-mesh NoC architecture will be presented and discussed in this paper to demonstrate the proposed platform.","PeriodicalId":282211,"journal":{"name":"The 2012 International Conference on Advanced Technologies for Communications","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131668027","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}
