A Novel Method of Channel Estimation for WCDMA
Xiaohu You · Dianzi xuebao · 2000
Estimation of Rayleigh fading channels using time multiplexed pilot symbols in W CDMA (FDD) is considered.Method of interpolation on a second-order curve using the instantaneous channel estimation of two successive slots based on least squa re method is presented.It is demonstrated by computer simulations that the chann el distortion on data symbols in a slot can be estimated effectively compared to the method using simple linear interpolation,and the performance of the Rake co mbiner is improved especially in fast moving cases.
