With iterative decoding, most LDPC codes have a weakness known as error floor. In this work, we propose a fixed bits LDPC decoding scheme to improve the ability of LDPC transmission. The method is universal as it can be applied to any code/channel model/decoding algorithm and it improves performance greatly, without losing the code regularity, without changing the decoding algorithm. Simulation results show that the error floor performance also can be significantly improved with this decoding scheme.
