FIELD: radio communication systems. SUBSTANCE: base-station pilot signal generator shapes identifying pilot signal corresponding to base station and has intermediate-frequency amplifier/divider that functions to divide amplified signal arriving from digital modem; radio-frequency channel unit designed only for actually existing communication and used for upward conversion of frequency of first part of divided signal and its transmission; and also radio-frequency unit designed only for pilot signal transmission and for upward conversion of second part of divided signal and its transmission as identifying pilot signal corresponding to adjacent base station. EFFECT: enhanced effectiveness of active channel switching; facilitated maintenance. 37 cl, 9 dwg
