OFDM is regarded as a potential technology for CR systems and dynamic resource allocation is an important task in such systems. This paper focuses on the sub carrier and power allocation algorithms which are to maximize secondary users' transmitted data rate while adjusting the interference introduced to the PU band below a threshold and maintaining the total power under a limit. The issue of sub carrier allocation in multi-user CR networks is firstly discussed. Secondly, three sub optimal power allocation algorithms based on LWF (linear water-filling algorithm) which have less complexity than the optimal algorithm are proposed. Simulation results show that the power interference algorithm based on linear water-filling scheme (LWF-PI) offers the best performance among the sub optimal power allocation algorithms, which is the closest to the optimal scheme.","PeriodicalId":368130,"journal":{"name":"2011 Fourth International Conference on Intelligent Computation Technology and Automation","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116871132","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}

When raw CFA was subjected to alkaline hydrothermal zeolite synthesis, the Zeolite X (ZFA-X) and zeolite A (ZFA-A) were formed. ZFAs had a much greater ability than CFA to remove ammonia. The pH strongly influenced ammonia removal by ZFAs. The higher removal efficiency was achieved when operating at pH between 6.5 and 8.5 for the ZFAs. From ammonia solution of initial concentration equal to 100 mg/L, the removal percentage reached values of 18.4, 76.8, and 82.1%, respectively, for CFA, ZFA-A and ZFA-X at room temperature, pH = 7.5, sorbent dose of 15 g/L, and contact time of 0.5 h.
