Abstract
The large system limits of the probability of error for multiuser Decision Feedback Detectors (DFDs) are evaluated for synchronous CDMA. Both Successive (S-) and Parallel (P-) DFDs are considered, where the filters are optimized according to the Minimum Mean Squared Error (MMSE) criterion. A comparison of the analytical results with simulation shows that the large system results accurately predict the performance of systems with spreading gain ≥ 128 over a wide range of error rates. The results also show that the P-DFD error rate approaches the single-user bound at high Signal-to-Noise-Ratios (SNRs).
