A transmitting/receiving system including a transmitter/receiver and a retransmitter. The transmitter/receiver includes an antenna, a multiplexer, a mixer, a receiver, a transmitter, an IF processor, a DSP and a control module. The retransmitter includes an antenna, a transceiver and a controller. The receiver receives a main input radio-frequency signal. The transmitter transmits a main output radio-frequency signal. The transceiver receives the main input radio-frequency signal, transforms the main input radio-frequency signal into an intermediate radio-frequency signal, and transmits the intermediate radio-frequency signal. The IF processor receives the intermediate radio-frequency signal and processes the intermediate radio-frequency signal. The DSP processes the main input radio-frequency signal with the processed intermediate radio-frequency signal. The control module forms and transmits a control signal to the controller, which sets a frequency and a power level of the intermediate radio-frequency signal.
