FIELD: base station receivers of mobile communication systems. SUBSTANCE: proposed method and device depend for their function on signal compression by means of complex compressing sequence, elimination of signal power by using orthogonal code for measuring power of noise orthogonal to at least one of orthogonal codes out of plurality of channels, measurement of signal-to-noise ratio by receiving noise power from noise-power meter and signal power from signal-power meter. EFFECT: enhanced signal-to-noise ratio measurement accuracy; prevention of erroneous power control commands in backward channel. 29 cl, 6 dwg
