Abstract
Direct sequence code-division multiple access (DS-CDMA) and multicarrier (MC-) CDMA are two important CDMA schemes for high rate wireless communication. A novel linear per user minimum mean square error (PU-MMSE) detection technique for DS-CDMA with frequency domain equalization (FDE) based on the MMSE criterion applied per user is presented. It is shown by computer simulation that PU-MMSE outperforms conventional per carrier (PC-) MMSE for DS-CDMA with FDE in frequency selective block fading channel. The performance of DS-CDMA with PU-MMSE FDE can be further promoted by successive interference cancellation (SIC). Comparing to MC-CDMA with PU-MMSE FDE, DS-CDMA with PU-MMSE FDE has no performance loss and has much lower peak-to-average power ratio (PAPR).
