Deep fadings occurred as a result of multipath propagation because some sub carriers that loses its information as well as fading in a non-recoverable degree, and consequently results in a poorer system performance. Since the training speed of LMS algorithm used in estimation of channel coefficients in time domain for OFDM based systems is not generally sufficient to achieve the desired performance levels in training time defined by standards, a fuzzy logic based algorithm is adapted to get a faster performance. An application of fuzzy logic based high performance LMS algorithm for OFDM systems is investigated in this paper. The aim of the proposed method is to produce the required fuzzy rule base and fuzzy subsets for fuzzy logic controller in order to speed up the LMS algorithm. The generations of fuzzy rules are based on the comparison of estimated signal by equalizer or channel output. The obtained results of simulations show that the LMS algorithm based on fuzzy logic (F-LMS) increases the performance in OFDM systems significantly and converges to the performance of the RLS algorithm","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127716271","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}

Bearings only tracking algorithms are used because the range information is distorted in water.

The performances of both systems for different values of CFO are compared. Since the desired performance cannot be achieved by CFO tracking ability of conventional LMS for SC and MC systems used in time varying channels, a fuzzy logic based LMS (F-LMS) algorithm is proposed. CFO tracking performance with the proposed F-LMS algorithm becomes very close to the performance of RLS algorithm with a small and negligible increment in computational complexity. Computer simulations using conventional LMS, normalized LMS, modified LMS, variable step size LMS-DFE, B-LMS-DFE and conventional RLS-DFE algorithms are performed in SC systems. The same algorithms are also used in MC (OFDM) systems in which the channel is estimated in time domain then used in frequency domain channel equalizer. For performance comparisons, the HIPERLAN/1 (SC) and HIPERLAN/2 (OFDM) standards are used as the working platforms during simulations.
