Center node: "an augmented nonlinear complex lms for digital self interference cancellation in full duplex direct conversion transceivers"
  Abstract: In future full-duplex communications, the cancellation of self-interference (SI) arising from hardware nonidealities, will play an important role in the design of mobile-scale devices. To this end, we introduce an optimal digital SI cancellation solution for shared-antenna-based direct-conversion transceivers (DCTs). To establish that the underlying widely linear signal model is not adequate for strong transmit signals, the impacts of various circuit imperfections, including power amplifier (PA) distortion, frequency-dependent I/Q imbalances, quantization noise and thermal noise, on the performance of the conventional augmented complex least mean square (ACLMS) based SI canceller, are analyzed. In order to achieve a sufficient signal-to-noise-plus-interference ratio (SNIR) when the nonlinear SI components are not negligible, we propose an augmented nonlinear CLMS (ANCLMS) based SI canceller for a joint cancellation of both the linear and nonlinear SI components by virtue of a widely-nonlinear model fit. A rigorous mean and mean square performance evaluation is conducted to justify the performance advantages of the proposed scheme over the conventional ACLMS solution. Simulations on orthogonal frequency division multiplexing (OFDM)-based wireless local area network (WLAN) standard compliant waveforms support the analysis.
