In this paper, we propose an improved NLMS (INLMS) based MMSE adaptive detection algorithm that can choose different step size adaptively and can solve the conflicting requirement of existing NLMS based algorithms. Simulation results show that bit error rate (BER) performance of the proposed algorithm is better than existing algorithms with the same training sequence length. Also when the training sequence length is longer than the steady state length of existing algorithms, the BER performance of the proposed algorithm can be improved by increasing the training sequence length which can't be achieved by existing algorithms.","PeriodicalId":249652,"journal":{"name":"2010 IEEE International Conference on Ultra-Wideband","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126615804","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}

Maximum achievable information rates of SC systems over ultra wideband (UWB) dense multi-path channels unveil that residual inter-symbol interference (ISI) of FDE results in significant capacity loss. Therefore, we mainly focus on low complexity processing techniques of FDE to reduce residual ISI caused by spectral nulls. For cases of high spectrum efficiency, a time-frequency interleaved (TFI) structure of FDE to achieve high diversity by combining uncorrelated spectral components is proposed. For cases of low spectrum efficiency, a combination of FDE and M-ary bi-orthogonal keying (MBOK) is proposed to eliminate the residual ISI and further improve power efficiency under the measure of Eb/N0.","PeriodicalId":249652,"journal":{"name":"2010 IEEE International Conference on Ultra-Wideband","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128965962","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}

The tumor detection in a two dimensional breast model with dispersive characteristic properties of the breast organisms is numerically carried out.
