Abstract
In this paper, based on factor graphs and Laurent decompositions, we propose an iterative receiver of CPM signals over interference (ISI) channels. We adopt the Gaussian message passing to simplify the message passing in factor graphs. Compared with the conventional receivers with the minimum mean squared error (MMSE) frequency domain equalization (FDE) and the BCJR demodulator, the proposed algorithm has advantages in terms of complexity. And the proposed algorithm can achieve better performance with the convolutional code.
