FIELD: receiving many signals residing on single medium without allocating many processors for processing digital signals. SUBSTANCE: coprocessor incorporated in digital signal processor unit uses capabilities of orthogonal nature of modulated signals during correction process due to the fact that after reception only some real-imaginary values of received signals are suitable for demodulation; filtering coprocessor processes only these values to evaluate signal transmitted. Processing only these values for demodulation enables co[processor to process information within certain desired time space. EFFECT: enhanced reliability of coded (decoded) signal reception. 13 cl, 22 dwg
