| Abstract(in English) | Space-time transmit diversity (STTD) and space-time block codes (STBC) are the attractive techniques for high bit-rate and high capacity transmission. Recently, low-density parity-check (LDPC) codes have attracted much attention as the good error correcting codes achieving the near Shannon limit. The concatenation schemes of LDPC codes and STBC (LDPC-STBC), and Turbo codes and STBC (Turbo-STBC) have been proposed. The performance of the LDPC-STBC is better than that of the Turbo-STBC on a flat Rayleigh fading channel. The performance of LDPC code can be analyzed by density evolution (DE). In this report we analyze the performance of the LDPC-STBC using DE. Also, we optimize irregular LDPC codes for the LDPC-STBC using DE. From the numerical and simulation results, we show that the performance of the LDPC-STBC with the irregular LDPC codes achieve better error rate performance than that with regular LDPC codes. |
