Concatenated LDPC and Differential Space-Time Block Codes

In this paper, we propose a multi-antenna system concatenated Low-density Parity-check (LDPC) codes and Differential Space-time Block codes (DSTBC), in which channel state information (CSI) is unknown to the transmitter and the receiver. The system performance is given through computer simulation, we can see that the proposed system not only provides transmit diversity gain but also coding gain.
