Diversity improvement for M -ary noncoherent frequency shift keying in impulsive reverberation noise
Andreas M. Maras, H.D. Davidson, A.G.J. Holt · Electronics Letters · 1985
The improvement in performance of M-ary noncoherent frequency-shift-keying (NCFSK) signals transmitted through a Rayleigh-fading channel computed by additive impulsive reverberation noise; a situation typically arising in active sonar, with diversity is demonstrated via the error probability expression. It is also shown that there is a limitation to diversity improvement.
