This paper proposes a novel three-point interpolation discrete Fourier transform for accurate power system frequency measurement. The accurate formula of the proposed frequency measurement method is derived by using the maximum sidelobe decay windows. Moreover, the influence of white noise on the proposed frequency measurement is analyzed by deducing the expression of frequency measurement variance...
Faster than Nyquist optical communication system recently attracts more and more attentions because of its higher spectral efficiency than ordinary Nyquist systems. In this work, we propose a modified-Viterbi and Viterbi phase estimation (VVPE) carrier phase recovery (CPR) scheme which shows an effective capability of reducing the cycle slips induced by inter-symbol interference (ISI) in a fast-than-Nyquist...
