摘要
Abstract
A soft-iterative channel estimation approach using superimposed training sequence was proposed.A periodic training sequence was added（superimposed） to user′s information sequence at the transmitter.In the channel estimation process the soft-iterative approach was adopted.By utilizing the soft output of channel decoder from receiver to calculate the one-order statistical quantity and return it to channel estimator,the channel estimation accuracy and the utility rate were improved due to eliminating the interference from the unknown data.Simulation results show the benefits of the proposed approach on the channel estimator,bit error rate（BER） performance and power efficiency.关键词
