Performance Analysis of STBC-OFDM System with Cascaded LDPC Coding
Guang Hui Zhao · Journal of Liaoning University of Technology · 2009
The STBC-OFDM system concatenated the Low Density Parity Check(LDPC) coding was proposed.The system model was constructed,the coding and decoding arithmetic of the STBC-OFDM system was described in detail.At last,the LDPC-STBC-OFDM system was simulated and compared with non-LDPC system by using MTALAB.The results expatiated that the STBC-OFDM system with cascaded LDPC coding had better performance than that of non-cascated LDPC,achieved a coding gain of 3.5 dB at BER=0.02 compared with the one of non-cascaded codes,and the BER performance got better and better as the SNR increased.
