Wideband-FM demodulation for large wideband to narrowband conversion factors via multirate frequency transformations

Wenjing Liu, Balu Santhanam

Abstract

Existing approaches for wideband FM demodulation are based on negative feedback, frequency tracking or multirate signal processing and heterodyning. Prior work that utilizes multirate frequency transformations for wideband-FM demodulation is impractical for large wideband to narrowband conversion factors such as those needed in DRFM systems. In this paper, we present a frequency transformation approach to wideband FM demodulation, using multirate systems, that can accommodate large conversion factors.
