Abstract :
A generalized symbol-rate-increased (GSRI) pragmatic adaptive trellis coded modulation (ATCM) applied to a multi-carrier CDMA system with bi-orthogonal keying is analyzed. In, an efficient ATCM scheme using GSRI-TCM has been proposed. However, since the modulation and coding selection is based on the ideal SNR estimation method, performance evaluations employing practical channel estimation scheme is desired. In this paper, we investigate the performance of the multi-carrier CDMA with GSRI ATCM employing practical SNR estimation. The performance evaluations on a multi-path fading channel are presented.
