Space-Time LDPC with Layered Structure for MIMO Systems
(2004) IEEE Wireless Personal Multimedia Communications (WPMC) 2004- Abstract
- In this paper, we incorporate the layered structure with low-density parity-check codes (LDPC)
to develop a quasi-block diagonal LDPC space-time structure. The lower triangular structure of
the parity check matrix introduces correlation between layers. In addition, each layer, as a part
of the whole codeword, can be decoded while taking information from other undetected layers to
improve the decoding performance. Belief propagation of the current layer is stopped as soon as
those parity checks involving only the current layer and detected layers are satisfied. Simulation
shows that the proposed system outperforms the conventional V-BLAST by 0.5 dB at WER=1%.
