Limited Feedback Method and Apparatus for Two-Way Wireless Relaying Channels with Physical Networking Coding

摘要

the present invention is a two-way relay channel in the Physical Network Coding for limited feedback method and apparatus for initiating. According to the present invention, PNC (Physical Network Coding) as a method for the parameters according to feedback channel to the two terminals in the repeater for interactive two-way system using a relay, (a) the minimum distance between the sex shops according to the modulation level (minimum distance) of the ratio (Ratio) quantizing the phase difference information of the two-way channel of the two terminals in consideration of whether or not it has the a cycle; And (b) comprises the step of transmitting feedback information includes at least one of the phase difference information and the two terminals of the transmission power allocation information to the two terminals in a restricted number of bits, the phase difference information in accordance with the modulation level feedback method that determines the number of bits for the bit number, or the transmission power allocation information is provided for. ;
