Abstract: PURPOSE: A digital TV relay system is provided to offer a digital broadcasting service with good quality by amplifying a digital broadcasting signal transmitted by a broadcasting station and retransmitting it. CONSTITUTION: A filter(114) filters an RF(radio frequency) signal. Demodulators(100,106) convert the filtered RF signal to an IF(intermediate frequency) signal and output an MPEG(moving picture expert group) signal. Modulators(101,107) channel-codes and modulates the MPEG signal and outputs an IF signal. Frequency converters(102,108) convert the IF signal to an RF signal of an allotted broadcasting channel. Power amplifiers(103,109) amplify the power of the RF signal. A corrector(105) calculates a compensation value to compensate for a nonlinear error of the RF signal and provides it to the modulators(101,107). A controller(104) controls the system.
