Performance bounds for DS/SSMA systems with binary noncoherent signaling schemes
The authors investigate the performance of direct-sequence spread-spectrum (DS/SSMA) communications systems with binary noncoherent signaling schemes, using complex signature sequences. Upper and lower bounds on the probability of bit error (p.b.e.) are obtained for differential-phase-shift-keyed (DPSK) signaling with differentially coherent demodulation and frequency-shift-keyed (FSK) signaling with noncoherent demodulation. The probability density function (p.d.f.) of the multiple user interference (MUI) is obtained for deterministic complex signature sequences. Upper and lower bounds are obtained by utilizing appropriate shifting procedures on the p.d.f. Numerical results are presented for some complex signature sequences, as well as binary sequences, with binary DPSK and FSK data modulations. Results show that complex sequences have good performances in noncoherent signaling schemes.<>
