SOLSM Channell Estimation for W-CDMA

摘要

Estimation of Rayleigh fading channels using item multiplexed pilot symbols in W-CDMA (FDD) is considered. Method of interpolation on a second-order curve using the instantaneous chain estimation of two contiguous slots based on least square method (SOLSM) is presented. It is demonstrated by computer simulations that the channel distortion on data symbols in a slot can be estimated effectively compared to the method using simple linear interpolation, and the performance of he Rae combine is improved effectively especially in fast moving cases.
