FIELD: radio engineering; demodulating sixteen-position quadrature amplitude keying signals.
SUBSTANCE: proposed demodulator that incorporates provision for maintaining equality of transmission gain in its cophasal and quadrature channels has first and second phase detectors, first and second low-pass filters, first through tenth comparators, 90° phase shifter, decoder, first through sixth counters, and two comparison units.
EFFECT: enhanced noise immunity.
