Abstract:
1. A method for canceling cross-talk in a cooperative wireless relay network including a base station (BS), a relay station (RS), and a mobile station (MS), comprising a processor for performing the steps, comprising the steps: estimating a coupling channel between a transmit antenna and a receive antenna, wherein the transmit antenna and the receive antenna are colocated at the RS; determining cross-talk interference based on a previous transmitted signal by the transmit antenna, and the coupling channel; subtracting the cross-talk interference from a currently received signal by the receive antenna to obtain a residual signal, wherein for K-subcarrier orthogonal frequency-division multiplexing (OFDM), the received signal is represented by OFDM modulation, the received symbol vector over the k transmitting the residual signal as a next transmitted signal by the transmit antenna.
