FIELD: wireless electrical communications.
SUBSTANCE: in order to enhance quality of coherent demodulation in system use is made of subchannels which are not subchannels for pilot signals. To this end, corrected data received over main channel are used to obtain better estimate of pilot-signal channel which is then used for demodulating data channel.
EFFECT: enhanced precision of estimating phase and amplitude noise inherent to transfer channel.
