Decoding algorithm of π-rotation LDPC codes and its quantization issues
Shaoqian Li · Information technology newsletter · 2005
In this paper,firstly,it introduces the Normalized BP-Based algorithm and proves the good performance of decoding of the π-rotation LDPC codes based on this algorithm by simulations;then,it studies the quantization scheme for the algorithm of the π-rotation LDPC codes.Some simulation results are given,which show that almost the same performance as the floating-point can be obtained by designing properly quantization schemes under AWGN channels.
