Abstract

This paper presents a technique for communications in the presence of rapidly varying Doppler. The modulation selected for this application is differential phase shift keying (DPSK). A number of receiver structures are proposed and their performance examined. It is shown that reliable communications can be achieved even at a data rate as low as 75 b/s and a E_b/N₀ of only 4-8 dB without the use of a separate beacon receiver to track the frequency variations. SHF ship-board satellite communication is considered as an example
