A novel method of wideband acquisition and anti-sideband lock in PM receivers using FFT

A significant problem in a phase locked loop (PLL) is the initial acquisition. High resolution is a major requirement in phase modulation (PM) receivers; however, such accuracy is hindered by side band locking in the existing PM detectors. A Fast Fourier Transform (FFT) based anti-sideband locking scheme is proposed for wide band acquisition in PM receivers… CONTINUE READING
