Studies on Space-Time Block Codes with LDPC

Firstly, this paper gives a simple introduction of the encoding/decoding theory of LDPC and Space-time coding. And it carries out a detailed research and analysis on LDPC coding system and the space-time block coding system. Then, LDPC and space-time coding are combined. The performance of LDPC-STBC under AWGN channel is given through computer simulation. The simulation results show that this method can improve the coding performance. In addition, it indicates a detail comparison of the different types of LDPC code weight and STBC receiving ways.
