Frequency-Domain Block Signal Detection for Broadband Single-carrier Transmission
One-tap frequency-domain equalization (FDE) is known to significantly improve the bit error rate (BER)performance of single-carrier (SC) transmission in a frequency-selective fading channel. However, there is a big performance gap from the theoretical lower bound due to the presence of residual inter-symbol interference (ISI) after FDE. In this paper, to reduce the performance gap, we present a new frequency-domain block signal detection, which combines FDE with MIMO signal detection such as Vertical-Bell Laboratories layered space-time architecture (V-BLAST) detection and maximuM likelihood detection (MLD) employing QR decomposition and M-algorithm (QRM-MLD). The achievable average BEr performance using the frequency-domain block signal detection is evaluated by computer simulation.
