(c) To cause problems for those transmitters being far coverage (FC) area and (d) Heavy traffic of MW band.

In the high SNR region the performance is governed primarily by symbol Hamming distance and the product criterion achieves an optimal coding gain, while in the low SNR region it is achieved by the trace criterion. We also discussed the performance behavior in the moderate SNR region. Finally, simulation results show that the proposed criteria are effective by comparing the performances of different codes.","PeriodicalId":349930,"journal":{"name":"2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications","volume":"340 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123399370","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}
