Abstract

This paper presents a hybrid automatic repeat request (HARQ) scheme based on turbo product codes (TPC) error correction and self-detection. The TPC inherent error detection is used as an alternative to the conventional cyclic redundancy check (CRC) process and is utilized to implement partial retransmission. The proposed HARQ system attempts to identify the location of errors within the TPC codeword. Consequently, only parts of the codeword which are declared erroneous are retransmitted. The performance of the proposed TPC-based HARQ is evaluated with hard and soft decision decoding in additive white Gaussian noise (AWGN) channels. Packet combining and adaptive channel coding are also considered. The obtained results show that the proposed HARQ scheme provides higher or equivalent throughput when compared to CRC-based HARQ in most test scenarios.
