METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING IN WIRELESS RELAY SYSTEMS BY USING SUPERPOSITION CODING

摘要

the present invention is a wireless relay system in a multi-user using superposition coding a unicast method and apparatus for joint will . The base station overlap the first and second data message carrying the first and second information bit stream for the first and second terminals scheduled in the current scheduling time code transmission. The relay station transmits a third message carrying the extracted data to the second information bit sequence for the second terminal decodes the coded data, and overlapping the first and second terminals to the second information bit column The. First terminal, the superposition-coded data and the third data message reception and removal of the components associated with said second information bit stream is extracted from the superposition-coded data from the third data message, the first data message After obtaining the, decoding the first data message and extracts the first information bit sequence. The invention, improving the communication quality by providing a multi-link between the base station and the terminal and increase the yield data.
