SINGLE CHANNEL MULTI-REPEATER SYSTEM, CONCERNED WITH SAVING FREQUENCY RESOURCES BY MAKING REPEATERS HAVE DIFFERENT DELIVERING FREQUENCIES NOT TO INTERFERE WITH EACH OTHER

摘要

PURPOSE: A single channel multi-repeater system is provided to make repeaters have different delivering frequencies not to interfere with each other, thereby saving frequency resources while leaving remaining frequency resources for using as future resources. CONSTITUTION: A single channel repeater(100) comprises as follows. A demodulator(11) demodulates an RF(Radio Frequency) signal received from a receiving antenna(10), and converts the demodulated RF signal into a TS(Transport Stream) signal. A delay module(12) delays the TS signal by using a buffer memory or a gate, and outputs the delayed TS signal. A modulator(13) modulates the TS signal, and converts the modulated TS signal into an IF(Intermediate Frequency) signal. A channel converter(14) converts the IF signal into an RF signal. An output amplifier(15) amplifies the RF signal. A transmission antenna(16) delivers a main signal.
