ABSTRACT:
This invention relates to parallel architecture digital filter and signal receiver with spectrum spreading using such a filter, the filter may have p shift registers (Rp, Ri) with means for calculating a weighted sum of stored samples in the registers, p weighted sums (Skp, Ski) may be obtained and recombined with number p being, for example, equal to 2.
