Abstract

In this letter, we investigate the performance of space-time trellis codes in a time-varying channel of a multiple-access wireless system where symbols of a user are transmitted using parallel sequences. Using rank and determinant criteria, it is shown that space-time trellis codes originally designed for quasi-static channels are efficient codes for this system as well. Simulation results demonstrate that the proposed transmission scheme can exploit spatial and temporal diversities to achieve performance gains at practical decoding complexity levels.
