Design of LDPC code for uncorrelated Rayleigh fading channel using modified outage probability

ICT Express
In this paper, we propose a new design metric called modified outage probability (MOP) for protograph-based low-density parity-check (LDPC) codes over the uncorrelated Rayleigh fading channel.

Reliability-Ratio Based Weighted Bit-Flipping Decoding for Low-Density Parity Check Codes

, 2004
A novel reliability ratio based weighted bit-flipping decoding scheme is proposed for low-density parity-check codes. A coding gain of 1 dB is achieved in comparison to the weighted bit-flipping scheme, when communicating over an AWGN channel, while ...
