Abstract
In this paper, channel estimation and data detection under non linear time-varying channel are
investigated. The model of non linear time varying channel that we focused on is known as switching
state space model (SSSM). This model combines the hidden Markov model (HMM) and the linear state
space model (LSSM). In this paper based on the EM approach, we propose a new iterative method for
joint data detection and channel estimation. Monte Carlo simulations show that the bit error rate
(BER) of the proposed scheme is close to BER of the Viterbi algorithm (VA) with perfect channel state
information (CSI).
