In this paper, we investigate the performance-complexity trade-off for two leading-edge channel coding techniques, namely duo-binary turbo-codes (DBTC) and block LDPC codes (BLDPCC). We assess their respective decoding complexity in terms power consumption and cycle delays, as a function of both the code rate and packet length, to derive a domain of suitability for both techniques. We also compare their capabilities to serve as mother codes for rate-compatible punctured codes (RCPC) and finally analyze their achievable throughput, as a function of the degree of parallelism.
