METHOD OF RATE-AWARE TWO-WAY RELAY COMMUNICATION FOR OFMD SYSTEMS

摘要

The present invention relates to a method of rate-aware two-way relay communication for an OFDM system and makes a target to solve a conventional weakness that should be aware by a relay node and a high complexity problem of an algorithm for selecting an antenna in a relay transmission system. According to the method, in a multi-antenna two-way rely system communicating in an OFDM scheme, a signal is selected which has high power for each sub-carrier by monitoring power of a signal received by each communication node, and the relay node amplifies and linearly combines a signal to transmit it to the communication node on the basis of a power allocation value matching a target rate of each communication node.
