CHANNEL GAIN ESTIMATION IN A RAKE RECEIVER USING COMPLEX WEIGHT GENERATION(CWG) ALGORITHMS

摘要

A channel estimation method which reduces the strain on resources of a RAKE receiver using a complex weight gain (CWG) algorithm. In one embodiment, a non-adaptive algorithm is used to average blocks of pilot symbols from several slots (320). In another embodiment, an adaptive algorithm implements sliding window averaging or a recursive filter. Using a CWG algorithm (325) reduces the memory and processor requirements of the RAKE receiver.
