PURPOSE:To perform communication with the same transmission quality as that of a reproduction relay system by compensating an interference noise added at each non-production repeater station by a reproduction radio station comprehensively in a hybrid relay system in which the non-reproduction repeater station is provided between a transmission radio station and a reproduction radio station. CONSTITUTION:A reference frequency oscillator 126 which generates a frequency that becomes the common divisor of the frequencies of plural local signals used in a frequency conversion function, and phase synchronous oscillators 117, 121, 125, 133, 136, and 139 which generate plural transmission/reception local signals used in the frequency conversion function by multiplying the output of the frequency oscillator 126 and synchronizes the transmission/reception local signals are provided in the non-reproduction repeater station 156, and adjacent channel passing interference generated at the non-reproduction repeater station 156 is set equally to wave distortion, and it is compensated by wave equalizers 153, 154, and 155 in the reproduction radio station. |
