Time-dependent performance of MSK, DPSK, and MFSK waveforms in aslow-fading nuclear disturbed channel

摘要

The author extends previous results and presents the performancenof several common waveform implementations in the presence of anslow-fading nuclear disturbed environment. Specifically, bit error raten(BER) performance data were generated as a function of time after burstn(TAB) for minimum shift keying (MSK), differential phase shift keyingn(DPSK), and M-ary frequency shift keying (MFSK) modulationntechniques for a variety of nuclear detonation scenarios. Data werengenerated for various combinations of forward error correction (FEC)ncoding, spread spectrum, and signal diversity techniques assuming anbroadband jamming threat
