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.
