Abstract :
The performance of frequency-hop spread-spectrum multiple-access networks using orthogonal M-ary frequency-shift keying modulation with noncoherent detection is analyzed under tone jamming, Rayleigh fading, and additive white Gaussian noise. A simple Gaussian model is derived for the multiple-access interference giving accurate fit to the simulation results with appropriately chosen correction terms. This approximation is then used to analyze the performance of the network under additional tone jamming. Both cases when the jamming tones fade and when they do not are considered
