Abstract :
In this paper, a novel superimposed pilot scheme is presented, which not only has the optimized MSE (mean squared error) of channel estimation, SINR (signal-to-interference noise ratio) and PAPR (peak-to-aver age power ratio) simultaneously, but also is robust to de-offset. The relationships of MSE and SINR with pilot parameters are analyzed through simulation. Comparison proves that the proposed pilot scheme has both high SINR and good robustness
