In this paper, we prove that the accuracy of time skew estimation increases as the number of overheard packet exchange from other neighboring nodes increases, and propose a light-weighted synchronization algorithm for multi-hop UANS, named as Improved Multi-hop time Synchronization for Underwater Acoustic Networks(IMSUAN). IMSUAN consists of three parts. The first one is to establish a time synchronization tree with the reference node as the root, and assign each node a tree level as low as possible. The second one is to synchronize with the parent node by dedicated three-time handshake and overhear exchange packets from parent and neighboring nodes. The third is to filter the inaccurate time-stamps of the overheard synchronization packets. In the paper, we establish a simulation platform in OPNET to evaluate the performance of IMSUAN. Simulation results show that the performance of extended Tri-message, MSUAN and IMSUAN are the same when no overhearing exists. However, when overhearing is possible in a random topology, the performance of IMSUAN can be 60% better than extended Tri-Message and 40% better than MSUAN.","PeriodicalId":342639,"journal":{"name":"2013 International Conference on Wireless Communications and Signal Processing","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114484730","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, while users having mutual correlated channels caused by the increased density of smart phones nowadays, this method would make correlated subspaces unused by data transmission for any user, and cause the reduction of overall throughput. To address the corresponding issue, we in this paper study the efficient precoding scheme that can eliminate the multi-user interferences as well as maximize the system capacity for MU-MIMO system in the spatially low scattering channel environments. Unlike the existing methods, our approach allows high-QoS-requirement users' precoding matrices to lie in the correlated subspaces between the channels of these primary users and the rests, so that more data streams can be transmitted to the primary ones simultaneously. In the mean time, in order to avoid the multi-user interferences, we require that every correlated channel can only be occupied by one user's precoding matrix. Following the aforementioned principles, we propose a Correlated Channels Utilized Precoding (CCUP) scheme for MU-MIMO system. Under this scheme, we also propose a different utilizing criterion of correlated subspaces to satisfy the networks with same-QoS-requirement services, in which every user's precoding space can be broadened by adopting partial correlated subspaces, termed Fair CCUP (F-CCUP) scheme. Simulation results show that while keeping no multi-user interferences, our proposed CCUP scheme can greatly increase the number of allowed independent data streams, and improve the overall capacity of MU-MIMO system in spatially correlated propagation environments compared to the existing approach.","PeriodicalId":342639,"journal":{"name":"2013 International Conference on Wireless Communications and Signal Processing","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115507586","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}
