Abstract

This letter proposes a new optimal ordering method which minimizes error propagation in the vertical Bell-lab Layered Space-Time (V-BLAST) by exploiting the whole filter output. A suboptimal ordering metric is also proposed which requires much reduced complexity compared to the optimal ordering metric. We also derive a simplified version of the suboptimal ordering metric which achieves a significant performance gain over the conventional ordering with minor additional complexity.
