The statistical Bayesian channel estimation was investigated in the CDMA TDD mode. The Bayesian estimation is derived through statistical analysis and it is shown to be equivalent to the maximization of the a Posteriori Probability. A modified approach to combine the Bayesian estimation and the hard gating is proposed. Simulation results demonstrate that it improves the estimation accuracy and keeps low computational complexity.
