Abstract
This paper investigates the performance degradation resulting from multitone interference
of orthogonal, frequency hopped, noncoherent M-ary frequency-shift keyed receivers (FH/MFSK)
where the effect of thermal and other wideband noise is not neglected. The multiple, equal power
jamming tones are assumed to correspond to some or all of the possible FH M-ary orthogonal
signaling tones. Furthermore, the channel is modeled as a Ricean fading channel; and both the
signaling tones and the multiple interference tones are assumed to be affected by channel fading.
It is also assumed that channel fading need not necessarily affect the signaling tones and the
interference tones in the same way. When the information signal power exceeds the power of the
individual interference tones, poorer overall system performance is obtained when the multiple
interfering tones experience fading. This trend is accentuated as M increases. When the
information signal experiences fading, the effect of fading multiple interference tones on overall
system performance lessens, and for a Rayleigh-faded information signal, fading of the multiple
interference tones has no effect on overall system performance regardless of M.
