—This paper studies receiver techniques for nonlinear amplifier distortion compensation in an OFDM relay-assisted cooperative communication system. The system model includes a nonlinear amplifier at the amplify-and-forward relay, modeled as a solid state power amplifier (SSPA). A maximum ratio combiner (MRC) is introduced that includes the effects of the(More)
We study alternative signal designs for electric vehicle (EV) charging control based on vehicle-originating-signals (VOS). In the original VOS approach, the need-for-charge signal is proportional to a ratio between required and available charging times which results in a convex signal. We therefore consider alternative signal designs with different(More)
