Time and Frequency Acquisition of FH-MFSK Signals with Random Data: Hopping Down the Most Likely Trail

A unified approach based on maximum likelihood estimation for time and frequency acquisition of frequency-hopped M-ary FSK signals with random data is presented. Algorithms for estimation of frequency and joint estimation of time and frequency are derived for the cases in which: (1) the data sequence is treated as a set of nuisance parameters; (2) the data… (More)
