Abstract :
We present an improved thresholding LDPC decoding algorithm which outperforms the split-row and original split-row threshold decoders with a small increase in hardware. Simulation results show that the algorithm provides 0.27- 0.50 dB coding gain over split-row, 0.10-0.20 dB over split-row threshold, and is within 0.08-0.13 dB of SPA. Compared with the original threshold algorithm the check node processor´s gate count is increased by 3% while total chip area is kept the same.
