Abstract


Bit-interleaved coded modulation with iterative decoding (BICM-ID) can get high coding gain no matter on the additive white Gaussian noise (AWGN) channels or on the fading channels. And comparing with turbo trellis code modulation (TTCM), BICM-ID has low complexity, can be easily implemented on the hardware. It has been widely known that for fixed interleaver and channel encoder, signal mapping plays an important role in determining the error performance of a BICM-ID system.Doping mapping design for BICM-ID system with 8psk signaling over the AWGN channel is concentrated on in this thesis. The thesis is organized as follows:1. The BICM-ID system model is introduced, containing analysis of the transmitter structure and the receiver structure.2. We introduce the principle of the EXIT(Extrinsic Information Transfer)chart, we also use EXIT chart to analyze the iterative processing of BICM-ID system with MSEW mapping and Gray mapping.3. The BICM-ID system with doping mapping is studied. Taking Gray mapping and MSEW mapping for example, we simulate the system performance with different doping rate and get respective EXIT chart, the latter can give very good explanation to the performance.
