This paper provides a framework for error rate performance analysis of M-ary phase-shift keying (MPSK) systems with improper phase estimation over some common fading channels obeying Rayleigh, Rician, or Nakagami-m distribution. In addition, the channel is also perturbed by additive white Gaussian noise (AWGN). The phase distortions considered in the paper are random, unbiased, i.e. having zero-mean,...
The performance of discrete-time Decision Directed (DD) and Non-Data Aided (NDA) first-order Phase Looked Loops (PLL) for a QPSK modulated signal is evaluated under the disturbance of thermal noise and 1/f2 phase noise. A well known continuous-time model is presented that closely approximates the loop??s behavior. Using the continuous time model, Fokker-Planck techniques are applied to compute the...
A novel algorithm for Signal-power-to-Noise-power ratio (SNR) estimation in AWGN channel is proposed in this paper. The relationship between SNR and the distribution of instantaneous phase (DIP) of BPSK signal is investigated, and the SNR estimator is constructed according to this relationship. Correlation coefficients are used to judge the similarity of the DIP between the theoretical one and the...
