Abstract :
In this paper, we investigate the performance of MC-CDMA with bi-orthogonal keying employing Generalized Symbol-rate-increased (GSRI) Pragmatic Adaptive Trellis Coded Modulation (ATCM). It is advantageous that the GSRI TC-MPSK can arbitrarily set the bandwidth expansion ratio (coding rate) and higher coding gain than the conventional pragmatic TCM scheme can be obtained. By changing the modulation scheme and the bandwidth expansion ratio, this scheme can optimize the performance according to the channel conditions. The performance evaluations by simulations on an AWGN channel and multi-path fading channels are presented. It is shown that the proposed scheme has remarkable throughput performance than that of the conventional scheme.
