摘要：
An iterative decoding scheme for the serial concatenation of a convolutional code and a GMSK modulator is presented. The maximum aposteriori probability (MAP) algorithm accepting a priori information and providing a soft-output is applied to a GMSK differential phase detector (DPD). An iteration scheme is devised to act between the demodulation and the subsequent. convolutional decoder.: Compared with the traditional decoding method, simulation results of the new scheme show an evident improvement in overcoming the severe intersymbol interference of GMSK signals.
