Abstract

Collaborative coding multiple access (CCMA) schemes permit simultaneous high-rate communications by two or more users in the same bandwidth with modest synchronisation requirements. However, the performance of CCMA systems degrades when the transmission of the composite signal takes place over fading channels. In this paper, we propose the utilisation of CCMA schemes combined with space-time block coding (STBC) for multi-user communications over power line channels. It is shown that for the same composite rate a CCMA/STBC scheme using three transmitting phases gives a gain of 10 dB over the use of a CCMA system without diversity when the channel is corrupted by impulsive noise, and a gain of 20 dB when the channel noise is additive white Gaussian (AWGN).
