Multiple-User Interference in a Frequency-Hopped Spread-Spectrum Communication System Using Differential Phase-Shift Keying

摘要

A design of short Reed-Solomon hopping sequences which have excellent correlation properties is proposed. Within the design, any two sequences will have at most one partial hit or one full hit when used asynchronously. The behavior of a near-optimum differential phase-shift keying (DPSK) receiver with multiple-user interference over a non-fading channel is discussed. Bit error rates for the receiver with single interference in one chip and the receiver with single interference in J distinct chips are found. Finally, generalization of the multiple-user interference model is considered.
