METHOD AND ARRANGEMENT FOR SIGNAL DISTORTION MITIGATION

摘要

A method for signal distortion mitigation in a communication device with at least one transmitter in a communication system, generating a signal for transmission for each of the at least one transmitter; performing Peak-to-Average Power Ratio (PAPR) reduction and spectrum shaping of each of the generated signal to provide a distorted signal for transmission; determining signal distortions of the distorted signals, and precoding the determined signal distortions. The method further generating a composite signal for transmission based on the precoded determined signal distortions and the generated signal for transmission, to provide a composite signal, and transmitting the composite signal to at least one receiving communication device, wherein the precoding enables mitigating the signal distortion impact on the at least one receiver.
