Performance Analysis of FFH/MFSK Receivers With Self-Normalization Combining in the Presence of Multitone Jamming

Abstract—An analytical study is presented for the performance of fast frequency-hopping (FFH) self-normalized orthogonal-ary frequency-shift-keyed (MFSK) noncoherent receivers in the presence of multitone jamming. The multiple equal-power jamming tones are assumed to correspond to some of the possible FFH /-ary orthogonal signaling tones. It has been shown that a higher diversity order (the number of hops per symbol) improves significantly the worst case performance of the self-normalized receivers against multitone jamming and reduces the fading effect of jamming tones. There exists an optimum value of modulation order ( ) that maximizes the worst case performance of the self-normalized MFSK receiver. Index Terms—Fading channel, frequency hopping, multitone jamming.
