Differentially Coherent Detection of QASK for Frequency-Hopping Systems - Part II: Performance in the Presence of Jamming

The performance of differentially coherent detection of frequency-hopped QASK in the presence of partial-band noise and partial-band multitone jamming is presented. In each case, the worst case jamming strategy is determined which consists of specifying the worst case partial-band fraction and the corresponding maximum average error probability. The results obtained are compared with those of
M
-ary FH-DPSK operating in the same jamming environment.
