Optimized Squeezing Operation for Phase-Shift Keying Quantum State Discrimination
IEEE Access, 2022 Many receiver designs have been studied in the past to discriminate Phase-Shift Keying (PSK) quantum states that are used to encode information before transmitting over the communication channel.

Phase Jitter in MPSK Carrier Tracking Loops: Analytical, Simulation and Laboratory Results [PDF]
, 1997 A performance characteristic of M-ary phase shift keying (MPSK) receivers is the variance of the phase error between the received and recovered signal carriers. For binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) loops utilizing

A Unified Theory of Intrachannel Nonlinearity in Pseudolinear Phase-Modulated Transmission
IEEE Photonics Journal, 2010 It is shown that the phase distribution of the field and the detection scheme strongly affect the strength of the nonlinear impairments in phase-modulated transmission systems.

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

Rotative quadrature phase-shift keying
Electronics Letters, 1992 A rotative quadrature phase-shift keying (RQPSK) modulation scheme is proposed. By rotating the QPSK signal constellation by pi/2, either clockwise or anticlockwise, during a symbol duration, the conventional QPSK scheme can be modified to transmit 3 bits per symbol to achieve both power and bandwidth efficiency.
