Under ensuring the quality of service (QoS) of the PUs, the precious spectrum resource can be utilized by maximizing the sum-rate and optimizing power allocation of the SUs. On the other hand, the multiple-antenna mobile user case needs further investigating for the problem mentioned above. Thus, we simply term this setting as multiple input multiple output multiple access channels (MIMO-MAC) in the CR Networks. To effectively and efficiently optimize the power allocation of the SUs, a tight pair of upper and lower bounds, as an interval, of the optimal Lagrange multiplier is proposed. Furthermore, a novel water-filling is proposed for the inner loop computation of the proposed problem. It is shown that the new water-filling can obtain the exact solution with a few finite computations. Therefore, not only is convergence of the proposed algorithm guaranteed, but efficient computation is also provided by the proposed algorithm.","PeriodicalId":344851,"journal":{"name":"2013 IEEE International Wireless Symposium (IWS)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131657806","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}
