English abstract:
Interference between users in adjacent channelsnegatively affects throughput of mobile networks. In this paperwe aim at cancellation of interference caused by a nonlinearpower amplifier in a generalized orthogonal frequency divisionsystem. We propose an interference cancellation method tosubtract these out-of-band emissions from the received signal.In contrast to state-of-the-art methods, our proposed methodemploys over-the-air estimation of power amplifier model para-meters together with a particular frequency domain filteringmethod that allows to generate the required training data. Theproposed interference cancellation method is also verified by anexperiment on a software defined radio test bench.
