FIELD: radio engineering; demodulation of sixteen-position quadrature amplitude keyed signals.
SUBSTANCE: newly introduced in prior-art sixteen-position quadrature amplitude keyed (KAM-16) signal demodulator are fifth and sixths counters and phase error correction unit; there units make it possible to execute following new operations with signal: counting of signal points within count interval, their quantity enabling evaluation of phase error due to unwanted lock-on; correction of calculated phase error in phase error correction unit.
EFFECT: enlarged functional capabilities.
