FIELD: measurement; testing.
SUBSTANCE: invention relates to communication engineering and can be used as a processor for a radio receiver that is capable of processing a direct sequence spread spectrum signal (DS-SS signal). To this end, the processor includes a demodulator, a digitiser, correlator (64), and a chip-matched filter, wherein the digitiser sample rate is selected to take a plurality of samples of each incoming chip at differing points thereon compared to sample points on an adjacent chip and to sample the chip at a non-integer multiple of the chip rate, wherein the chip-matched filter is arranged to filter the output of the digitiser. Sample selection unit is arranged to select a single sample from the filter for input to each tap of the correlator, the selected sample being chosen as that nearest in time to a desired ideal time in relation to a timing reference point on the chip.
EFFECT: technical result consists in increasing monitoring efficiency by improving the quality of correlation.
