| Abstract: | A bit interleaved coded modulation(BICM) scheme was introduced,with iterative decoding using soft decision feedback.So it is named as BICM with iterative decoding(BICM-ID).By using BICM-ID,it could yield a better coding gain over Rayleigh fading channels without bandwidth expansion for communication systems,and resist the noise and fading as well.Simulation results show that the BICM-ID scheme can effectively improve the receiving performance for communication. |
