Iterative decoding for layered space-time codes

Dual antenna-array systems provide very high capacity compared to single antenna systems in a Rayleigh fading environment. If the transmitter does not have the channel state information, to utilize this high capacity, space-time codes must be employed. We present the interleaved diagonally-layered space-time (DLST) code with iterative decoding. Interleaved DLST codes with iterative decoding achieves a data rate proportional to the number of antennas with a good performance and low decoding complexity. We analyze the performance of interleaved DLST codes assuming maximal likelihood decoding, and propose the corresponding code design criterion. We also perform simulations to verify the analysis
