Detection of Fast, Noncoherent, Frequency-Hopped FSK
C. J. Waylan · IRE Transactions on Communications Systems · 1975
As technology becomes increasingly able to meet the requirements, interest in faster, noncoherent, frequency-hopping rates to reduce detectability of communications has heightened. The question of what dectect on method is to be used for transmissions which have been frequency-hopped at a rate faster than the data rate thus arises. This concise paper presents the derivation of the optimum detector for binary frequency-shift keying (FSK) noncoherently frequency-hopped at an integer multiple of the data rate. The performance of this detector and simpler implemented nonoptimum detectors are examined by simulation.
