چکیده
Coded modulation is a bandwidth efficient schemes that combines the function of coding and modulation. In this paper a comparative study of various modulation techniques such as Trellis coded modulation(TCM),Turbo Trellis coded modulation(TTCM),Bit-Interleaved Coded Modulation(BICM) ,Iterative Decoding Bit-Interleaved Coded Modulation(BICM-ID) and Superposistion Coded Modulation schemes over Gaussian and Rayleigh Fading channels is made and presented in the context of 8 level PSK. The study is based on the comparison made for associated decoding complexity; block length and bandwidth efficiency for static channel scenario. It is shown that SCM constitutes the best compromise scheme, followed by BICM-ID. Index Terms : SCM –Superposistion Coded Modulation ,BER-Bit Error Rate, PAPR-Peak to average power ratio, OFDM-Orthogonal Frequency Division Modulation. BICMID -Bit Interleaved coded Modulation for Iterative Decoding.
