FIELD: multiple-station access radio communication systems using time-shared channel multiplexing and frame structures for communication between stationary, mobile, and portable radio sets of such system. SUBSTANCE: system has base station and many remote radio for communication within time intervals of time shared channel; base station is provided with sync signal transmitting facilities for determining position of time intervals; each remote radio set has power amplifier with linearizing facilities. Channel has predetermined linearizing time intervals 120 to transmit adjustment signals distributed in spaces among other intervals; each remote radio set has facilities for shaping adjustment signal within linearizing time interval and for linearizing its power amplifier during this time interval up to and irrespective of transmission of signals during one of other mentioned time intervals. EFFECT: improved design. 12 cl, 4 dwg
