摘要
A method of enhancing performance using hierarchical modulation in a distribution relay system is provided to expand an area of high speed data without requiring an additional time slot, thereby obtaining a gain of increasing yield. A base station transmits a signal through a hierarchical modulation method. The first relay and the second relay receive a signal transmitted from the base station. The first relay retransmits all the received signals to a terminal through the hierarchical modulation method. The second relay retransmits only a part among received signals to the terminal. The terminal performs a demodulation process.
