【Abstract】 This paper introduces bit interleaved coded modulation with iterative demodulation and decoding(BICM-ID)and studies the extension of such schemes with joint coded modulation diversity.BICM-ID with signal space diversity can effectively resist the noise and fading over Rayleigh fading channels.Furthermore,simulations results show that a well considered choice of the rotation angle leads to a signi?cant gain over conventional BICM.更多还原
