%X Firstly it is proved by simulation that the Low Density Parity Check(LDPC) code has sound performance under block fading channel when decoded by general belief-propagation algorithm. Then based on its special iterative nature, the improved belif-propagation algorithm is proposed under block fading channel with channel estimation in every iterative step. The simulation demonstrates that the proposed algorithm can effectively reduce the iterative times of decoding.
