Abstract: The advantage of differential space-time block codes (DSTBC) over conventional space-time block codes (STBC) is that the former does not require perfect channel state information (CSI). The trade-off is a penalty of approximately 3 dB in performance. Due to the recursive structure of DSTBC, iterative demodulation and decoding can be performed on a system of concatenated component DSTBC encoders. This paper proposes the parallel concatenation of two DSTBC blocks separated by an interleaver. It is shown that the 3 dB penalty can be sufficiently recovered within a few iterations. © 2005 IEEE.
