M-PSK Demodulator With Joint Carrier and Timing Recovery [PDF]
IEEE Transactions on Circuits and Systems II: Express Briefs, 2021 In this brief, we propose a new digital receiver for Phase-Shift Keying (PSK) modulation based on the integration of the conventional digital Costas Loop circuit with a new timing recovery method. The timing recovery is applied to the PSK demodulator using an Iterative Learning Control (ILC) law and it is based on the minimization of the intersymbol ...
