Performance of low-rate turbo code using codebook based transmit diversity for DFT-precoded OFDMA

This paper presented the average BLER performance using the combination of low-rate turbo code and codebook based transmit diversity associated with the IDDCE for DFT-precoded OFDMA. Computer simulation results showed that the average BLER of 10 −2 for R = 1/15 (1/9) is achieved at the average received SNR of approximately −9.8 (− 8.2) and −11.8 (−10.4) dB for the N Tx = 2- or 4-antenna codebook transmit diversity, respectively, with N Rx = 4-antenna receiver diversity using the IDDCE. In conclusion, we confirmed the effectiveness of the combination of low-rate turbo code and codebook based transmit diversity using the IDDCE for achieving the very low required average received SNR satisfying the target average BLER.
