Abstract :
Performances of serially concatenated continuous phase modulation (SCCPM) over ISI channels are studied. An Improved iteratively detected receiver of SCCPM over ISI channels is proposed, which improves the performance from the two aspects of equalizer and iterative method. An improved iterative interference canceller (IC) for SCCPM is proposed. In order to solve the problem of positive feedback during the iterative detection of SCCPM with short frame, an iterative method based on weighted exchange of extrinsic information is proposed. Simulation results show the improved receiver is more effective than classical receiver over ISI channels.
