Abstract
Several diversity combining techniques are considered for frequency-hop communication systems with M-ary orthogonal signaling and noncoherent demodulation in the presence of uniform Gaussian noise and partial-band Gaussian noise. Some of the results apply to general (non-Gaussian) partial-band interference. Among the techniques described are square-law combining, linear combining, and linear combining of the outputs of the cascade of an envelope detector followed by a clipper. The primary goal is to find combining techniques which perform well in an unknown or changing interference environment.Keywords
