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...
A novel linear per user minimum mean square error (PU-MMSE) detection technique for direct sequence code- division multiple access (DS-CDMA) with frequency domain equalization (FDE) based on the MMSE criterion applied per user is presented, which approximately restores the orthogonality among the spreading sequences and reduces the interference. It is shown by computer simulation that the DS-CDMA...
