We propose three new high-rate coordinate interleaved STBCs and prove that they can achieve full-diversity with linear receivers for any optimally rotated square QAM constellation. Recently, Shang and Xia proved that the symbol rate of an STBC achieving full-diversity with a linear receiver is upper bounded by one complex information symbol per channel use (pcu). However, we show that with the use of coordinate interleaving, the proposed STBCs can exceed this upper bound to 4/3 complex information symbols pcu for two, three and four transmit antennas. For the symbol-by-symbol decoding of the proposed STBCs, we adapt the partial interference cancellation (PIC) group decoding algorithm recently proposed by Guo and Xia, and then further modify this decoder by applying successive interference cancellation (SIC) operation. Simulation results show that when linear receivers with minimum decoding complexity are used, the proposed STBCs achieve better error performance than their counterparts given in the literature.","PeriodicalId":344018,"journal":{"name":"2009 6th International Symposium on Wireless Communication Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133553509","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}

Based on the DVB-T standard, the DVB-H itself supports high data rate IP datacasting (IPDC) in dispersive broadcasting channels and enables low power consumption of portable mobile terminals (MTs) running in a robust mode. The error protection of the DVB-H link layer is based on a Reed-Solomon forward error correction coding scheme combined with an IP packet level cyclic redundancy check scheme. Targeted primarily at the digital video broadcasting error protection, however, the redundancy allowed in the DVB-H standard is not sufficient for the WBC service advertisements datacasting. To achieve reliable broadcasting in WBC, a smart cross-layer algorithm that interacts with the service layer's advertisements delivery protocol is proposed in this paper. With this new efficient solution, the ‘WBC over DVB-H' system is able to operate in a flexible and more reliable way, which requires no changes in the DVB-H standard.","PeriodicalId":344018,"journal":{"name":"2009 6th International Symposium on Wireless Communication Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125087339","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 may be implemented without physical compromise of any existing node, and poses problems in terms of reliable detection, as the resulting network properties may be difficult to distinguish from genuine routing improvements via new connectivity. However, as a wormhole attempts to encourage route formation in its vicinity, under network load an active wormhole will generate significant congestion around its endpoints. This paper proposes a novel routing approach which attempts to detect situations which may produce the poor performance characteristic of an ongoing wormhole attack, by making nodes take account of disturbance (the impact of a forwarding commitment on their peers), and diversify routes to attempt to find a wormhole-free path and reduce the influence of the attacker. An example security-sensitive deployment scenario is proposed, and simulation of this scenario is used to evaluate relative performance and energy costs of static and dynamic disturbance-based routing schemes, showing the schemes deliver significant performance improvements over shortest path routing.","PeriodicalId":344018,"journal":{"name":"2009 6th International Symposium on Wireless Communication Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116626403","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}
