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.

Effects of Imperfect Reference Signal Recovery on Performance of SC and SSC Receivers over Generalized Fading Channels [PDF]
This paper presents the study of the effects of imperfect reference signal recovery on the bit error rate (BER) performance of dual-branch switch-and-stay combining (SSC) and multibranch selection combining (SC) receivers in a generalized - fading ...

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

Error-bound formulation for multichannel reception of M-DPSK and pilot-aided M-PSK over Rayleigh-fading channels with postdetection combining [PDF]
Upper bounds for symbol-error probability are developed for multichannel reception of M-ary phase-shift keying (M-PSK) over frequency-flat Rayleigh-fading channels.

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.
