Abstract

This paper reviews multi-dimensional space-time multilevel codes (ST-MLCs). Basic construction methods, including conventional STCs. The space-time multilevel encoders partition a dimensional signaling space, which spans all transmit antennas. Complexity of detection/ decoding can be reduced by multi-dimensional partitioning. Space time multistage decoder for the proposed ST-MLCs is reviewed. The complexity of soft decision decoding to be significantly reduced by comparing a single level approach. In addition, significant performance gains are obtained over a single level approach.
