A novel channel estimation scheme with least square fitting
Changlong Xu, Xiao-Hu Yu · 2003
For continuous pilot CDMA system, the moving average filter is a conventional scheme for channel estimation, which can suppress the noise. To reduce the noise further, a novel channel estimation scheme that fits the output sequence of the moving average filter with least square approach is presented in this paper. The proposed scheme improves the accuracy of channel estimation and the BER performance of the coherent RAKE receiver, which is demonstrated by analysis and simulations.
