Weiling Wu · Journal of Chongqing University of Posts and Telecommunications · 2006
An iterative blind channel estimation and decoding algorithm for block fading channels is proposed.MAP and ML estimation expression is derived and it proves that MAP estimation is equivalent to ML estimation when SNR or the block length of the block fading channel goes to infinity.Simulation results show that there is a tradeoff between SNR and the block length of block fading channels which determine the performance of the proposed iterative algorithm.The impact of the block length of block fading channels on performance of the proposed algorithms is analyzed.
