Most of the interference graphs in the literature simply model the DATA and ACK traffic of a link by a single vertex. They fail to capture the link-directionalities. In fact, some instances of directional traffic can actually transmit simultaneously but are prohibited by the interference graphs. Thus, in our link-directional interference graph, a link is represented by two vertices, one for DATA traffic and the other for ACK traffic. We then apply a colouring algorithm in the I-graphs. The colouring results provide insights in order to boost network capacities in TDMA or FDMA ad-hoc networks. We show that the network capacities can be improved by 100% in a triangular topology and 33% in a lattice topology. Simulations also show that a distributed dual channel protocol assigning channels according to link-directionalities can boost the capacities by 70% in large-scale random networks. We believe this is a first paper in the literature to take into account link-directionalities in interference graphs.","PeriodicalId":370937,"journal":{"name":"IEEE GLOBECOM 2007 - IEEE Global Telecommunications Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115234728","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}

Different algorithms have been developed to improve the performance of the GSM system in severely interference limited scenarios exploiting the structure of the real-valued signal constellation adopted in GSM. For general complex-valued modulation, most known procedures are not applicable, as for a single antenna receiver the system gets overloaded and signals are not separable by e.g. linear operations. In this paper, cochannel interference mitigation with a reduced-complexity equalizer for intersymbol interference (ISI) channels in combination with an appropriate prefilter is considered. In order to enable SAIC for complex-valued modulation schemes, joint (multi-user) turbo equalization is applied. Performance is shown for different variants of the proposed basic scheme, where the GSM/EDGE system serves as an application example. One of the proposed variants is fully compatible to the packet radio transmission schemes of the GSM/EDGE standard and outperforms previously proposed SAIC algorithms for 8PSK.","PeriodicalId":370937,"journal":{"name":"IEEE GLOBECOM 2007 - IEEE Global Telecommunications Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115463327","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}

These mesh networks are referred to as wireless backhaul networks. Existing medium access control (MAC) protocols and scheduling algorithms are devised for wireless access. So although they have been adopted for the wireless backhaul networks, they do not yield good performance. In this paper, we propose a novel distributed scheduling algorithm, composed of a framework and a new utility function definition, for wireless backhaul networks. We show by analysis and simulation that in a long run the algorithm converges to the desired throughput allocation, which can be specified by the routing protocol in use to guarantee quality of service. Moreover, in terms of interference, we show that our framework maintains strong temporal correlation of interference, which is required to ensure proper channel predictions for scheduling gain and for distributed power control. Finally, simulation results reveal that the new algorithm takes advantage of the multi-user diversity in achieving high overall network throughput, when compared with the tree-structure algorithm.","PeriodicalId":370937,"journal":{"name":"IEEE GLOBECOM 2007 - IEEE Global Telecommunications Conference","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124194761","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}
