The New Decoding Method of Rate Compatible LDPC Codes Based on the IR-HARQ Schemes

Abstract

This paper proposes a new decoding method based on IR_HARQ scheme that uses rate-compatible LDPC codes as the FEC codes. And it can use the former decoding result, which can improve the performance of decoding scheme. This paper also evaluates the new decoding method by simulation. The results show that better performance both on system throughput and iterative times can be obtained.
