Abstract:
In this paper, a joint channel estimation and deeoding algorithm over doubly seleetive fading chan-nels is proposed. Based on Faetor Graph and Sum-Produet algorithm, the channel estimator and the deeoder,as independent information proeessors and using different internal/external update rules, are integrated into aunified FG model. Combined with particle filter algorithm, the channel parameters are tracked and estimatedin real time to realize the iterative message passing. The simulations show, under certain pilot interval andnumber of partieles, the perormanee of the algorithm is close to the known channel information with clear iter-ative process, and effeetively solve the low frequeney spectrum utilization problem.
