Security bound of continuous-variable measurement-device-independent quantum key distribution with imperfect phase reference calibration [PDF]
Phase reference calibration is a necessary procedure in practical continuous-variable measurement-device-independent quantum key distribution (CV-MDI-QKD) for the need of Bell-State Measurement (BSM). However, the phase reference calibration may become imperfect in practical applications.

Performance of qpsk system in the presence of pulse interference and noisy carrier reference signal [PDF]
The aim of this paper is the determining the system performance in detecting the QPSK signal. The error probability is determined when the signal, Gaussian noise, pulse interference and imperfect carrier phase recovery are taken into consideration. Phase

The letter analyses the performance of a two-link binary coherent phase-shift-keying (CPSK) communication system incorporating a direct phase regenerator (DPR) with imperfect carrier reference signals in the regenerator and the receiver. These references are extracted from the received signals by means of squaring loops.
