|Abstract: ||Group Layered Space-time architecture (GLST) combines space-time block coding and layered space-time processing, where the transmit stream is partitioned into different groups and in each group space-time block coding is applied. In the traditional receiver of GLST, group detection is applied first so as to suppress the interference from other groups and then decoding is performed for the desired group. In this paper, a novel detector is proposed, in which the entire groups are decoded first and then group detection is performed next. Theoretical analysis will demonstrate that the new detector can achieve a significant capacity gain compared to the traditional one. Simulation results will further show that the proposed detector can obtain at least 4 dB gain at a FER of 10-2, for instance.|
