Abstract
The effect of channel estimation errors upon the performance of an adaptive RAKE matched filter in a DS spread-spectrum system is studied in a two-path channel. A moving average filter with a memory of M bit intervals is used in the channel estimation. The estimation errors are mainly caused by channel noise and channel impulse response variations during the observation interval. The performance of the adaptive RAKE depends strongly on the selection of M. The optimal value of M depends on the signal-to-noise ratio and on the variation rate of the channel.
