	abstract = {<p>Despite the potential of beamforming approaches to mitigate self-interference (SI) in multiantenna mmWave full-duplex (FD) systems, limitations imposed by practical hybrid beamforming architectures make the problem quite challenging. We present a novel design for the partially-connected array structure with finite-precision phase shifters, based on maximizing the product of the signal-to-SI-plus-noise ratios (SSINR) at receivers. Analog precoders and combiners are designed first under this criterion, with SSINR measured at the analog combiners{\textquoteright} output. Using the effective channels for the found analog beamformers, the baseband beamformers are then obtained using the same criterion, but with SSINR measured at the digital combiners{\textquoteright} output. Simulation results show that the proposed scheme outperforms existing FD approaches in terms of spectral efficiency and residual SI, even with low-resolution phase shifters.</p>},

The focus is on hybrid architectures in which the analog subblock of the beamformer, common to all subcarriers, is fully-connected and based on phase shifters with finite resolution, to avoid frontend saturation by mitigating FD-induced self-interference in the analog domain.</div>},
