In this paper, an improved iterative detection method based on the exchange of weighed extrinsic information probability for serially concatenated continuous phase modulation (SCCPM) system is proposed. The method could reduce the phenomena of positive feedback during iterative detection by adaptively adjusting the extrinsic information probability. Simulation results show that the proposed method is effective and SCCPM systems with the improved iterative detection method have excellent power and bandwidth efficiency in Rayleigh fading channels.
