It can be verified by Monte Carlo simulations, when using the same extended Hamming code as TPC subcodes with coding efficiency of and the Bit Error Rate (BER) is 10−4 , the coding loss of the proposed adaptive algorithm is just about dB compared with Pyndiah’s iterative decoding algorithm using the fixed LRBs parameter in Chase decoder, but the average complexity of the proposed algorithm could be reduced about %. Key words: Turbo Product Codes (TPCs); Adaptive Chase algorithm; Least Reliable Bits (LRBs); Bit Error Rate (BER); Low-complexity
