Abstract
A technique is proposed for normalizing the multi-bit output of a RAKE receiver by automatically selecting from it fewer bits which are representative of the data in the CDMA signal. The invention is applicable to a CDMA signal in which the data is transmitted discontinuously and a pilot symbol is inserted into the data sequence and transmitted at a different power level. The proposed technique may be operated either on the basis that the power ratio of the pilot part of the CDMA signal to the data part is known, or alternatively without any knowledge of this power ratio. In both cases the pilot part is used to determine the bit position on which the normalization works, and also the fine adjustment of the data part of the CDMA signal.
