Baud Rate Estimation of FSK Signals Based on Wavelet Transform

Baud rate is an important quantity in telecommunications and reconnaissance. Current baud rate estimation algorithm mainly focuses on Phase Shift Keying (PSK) and Amplitude Shift Keying (ASK) signals. This paper proposes a new baud rate estimation algorithm of Frequency Shift Keying (FSK) signals based on wavelet transform. Comparing with limited number of baud rate estimation methods for FSK signals, this algorithm has better anti-noise performance and can still work in high dynamic circumstance, as demonstrated by extensive Monte Carlo simulations.
