A Study on Rate Estimation Scheme for Weighted Bit-Flipping Decoding of Rate Compatible LDPC Codes

Abstract (in Japanese) (See Japanese page) 
(in English) This paper considers a rate estimation scheme for Rate Compatible LDPC (RC-LDPC) codes. The authors have investigated some estimation schemes for RC-LDPC even through there is no side-information about code rates used at the transmitter. The previous schemes were based on Log-Likelihood Ratio (LLR) of Sum-Product decoders at the receiver. Because of too much computational complexity, more simple estimation schemes are expected to be developed. For the purpose of this, we focused on a simpler decoding scheme, Weighted Bit-Flipping (WBF) decoding which had been much attention by many reseachers recently. In this paper, a new rate estimation scheme is proposed and evaluated. Simulation results show that the proposed scheme has advantages of much effectiveness and potential estimating code rates.
