Summary:Analyses of worst-case partial-band noise jamming of binary
digital modulation are presented. Both noncoherent detection and
differentially coherent detection over slowly varying,
frequency-nonselective Rician fading channels are considered. The
analysis bridges the gap between earlier works by Viterbi and Jacobs
(1975) and by Omura (1981) for the limiting cases of Gaussian and
Rayleigh channels, respectively. The results complement those by Crepeau
(1990) for noncoherent binary transmission over the Nakagami fading
channel. However, the Rician channel model has more physical
significance since the parameter k is the ratio of scattered and
specular powers. It is shown that a partial-band (partial-time) jamming
strategy is optimum for all Rician channels with k<1 if the
signal-to-jamming power ratio is sufficiently high. On the other hand, a
full-band jamming strategy is the optimal strategy for k⩾1. Results
for the Gaussian and Rayleigh channels can be derived from the present
analysis in the limit as k=0 and k→∞, respectively
