FIELD: communications engineering.
SUBSTANCE: method includes configuring a receiver with possible waiting for receipt of communication channel at full data transfer speed, and signal from transmitter is sent to receiver. Signal is sent via communication channel with data transfer speed, different from full speed of data transfer, and at level of power for receipt at full data transfer speed. As a result receiver can not receiver communication channel at full data transfer speed. In receiver relation of received signal to noise is determined. Value of quality coefficient bit is determined ion basis of certain relation of signal to noise. Determined value of quality coefficient bit is sent to transmitter.
EFFECT: higher efficiency.
