Abstract
The demands for high data rates and spectrally efficient modulation techniques are increasing due to the evolution of multimedia service in wireless communication systems. Bit-interleaved coded modulation with iterative decoding (BICM-ID) is a bandwidth efficient transmission scheme, which is suitable for next-generation wireless communication systems. In order to exploit the time-varying nature of the channel, an adaptive iterative receiver for BICM-ID is proposed in this paper, which is adaptable in terms of selecting the iterative decoding algorithms according to the channel state information estimates available at the receiver. Simulation results show that the adaptive iterative receiver provides good performance with a lower decoding complexity both in AWGN and Rayleigh fading channels.
