A Novel Joint ML and DFE Scheme for V-BLAST System

摘要：

The use of multiple antennas at the transmitter and receiver results in enormous capacity increase. However,the performance of many current Space-Time architectures like Vertical Bell Laboratories Layered Space-Time (V-BLAST) is depend on the first sub-channel decodings performance. In this paper, we present a novel detection algorithm, which joint ML and DFE Scheme for the V-BLAST system. It can improve the V-BLAST systems performance by add ML modification module after the conventional detection scheme. It can also get the tradeoff between complexity and performance. Simulation result shows that the performance of the proposed scheme is better than that of conventional method.
