Abstract

In this paper, the performance of the Least Squares (LS) estimator along with turbo codes in OFDM is evaluated for the SUI channel models in the presence of AWGN. Turbo codes are used in this paper because of its BER performance close to Shannon limit. The iterative turbo decoder exchanges soft information between the component decoders. Maximum A Posteriori (MAP) and its simplified version Max-Log-MAP algorithms are used for the component decoders. The performance and complexity comparison is also made between the decoding algorithms. Moreover the effect of memory order on the performance of the decoding algorithms is also studied.
