Description
Summary:Frequency domain channel estimation and equalization w ied for D-STBC-SC-FDE systems with ampl-ify-and-forward relaying over frequency-selective fading channels, and a training-based least-squares channel estima-tion algorithm was proposed. The proposed algorithm ca estimate simultaneously both the direct channel S? D and the cascaded channel S? R? D at destination terminal assisted by Chu sequences, and can achieve the minimum mean square error. Monte Carlo simulation results confirm the proposed gorithm is correct and the available channel transmitting power allocation strategy affects the performance of channel estimation and equalization to a certain ex-tent.
