Abstract :
In this paper, a single antenna interference cancellation (SAIC) by means of sequential importance sampling (SIS) is studied. The contribution of the proposed algorithm is that the maximum a posteriori (MAP) estimates of the transmitted co-channel symbols is recursively computed without explicit channel information, and the joint posterior distribution of the channels is derived. The Symbol error rate (BER) performance of the proposed algorithm is evaluated and compared with that of other SAIC algorithms through computer simulation.
