摘要:
We propose a digital carrier recovery loop employing both a frequency detector and a phase detector for Wary phase shift keying (MPSK) systems. A new frequency error correction function is also derived to increase the acquisition range. It is shown through computer simulation that the proposed scheme can reduce the acquisition time at large frequency offsets, unlike the existing ones.
