摘要

"Filter conjugate and method for forming correlations between a stream of samples of the signal presented at a rate determined by a clock rate of the sample and a given binary code which has a plural.The age of binary bits, and,Method and apparatus to produce correlations between successive displacements of a sequence of numerical sample and at least one binary code that contains a plurality of bits binary "a filThe conjugate for use in a radiotelephone receiver which receives signals with code division multiple access (CDMA).The filter in conjunction produces pre combinations of input values to significantly reduce the number of operations of multiplication and addition, compared to conventional filters combined.Required to produce a value of correlation.This reduced number of required operations, along with a small number of delay elements required for desespalhar CDMA signals.Significantly reduces the overall power consumption of the filter in conjunction.The use of such a filter coupled in a device such as a cell phone, for example, would lead the way of life of the battery longer.
