  We propose a hybrid feed-forward receiver (HFFRE) for the discrimination of
binary phase-shift-keyed coherent states based on the appropriate combination
of a displacement feed-forward receiver (DFFRE) and a homodynelike setup
employing a low-intensity local oscillator and photon-number-resolving
detectors. We investigate the performance of the proposed scheme, also
addressing realistic scenarios in the presence of nonunit quantum detection
efficiency, dark counts, and visibility reduction. The present HFFRE
outperforms the DFFRE in all conditions, beating the standard quantum limit in
particular regimes.
