Multiuser detection (MUD) techniques are mandatory in direct-sequence code division multiple access (DS-CDMA) systems. They allow to mitigate multiple access interference (MAI) and hence increase the capacity and allow high data rates. Multistage parallel interference cancellation (MPIC) detectors are considered serious candidates for practical implementation showing a good tradeoff between performance...
This paper deals with the chip-level equalization technique for large area synchronized-code division multiple access (LAS CDMA) system communications. In the downlink of LAS CDMA, frequency-selective multi-path channel often destroys the orthogonality of spread codes at receivers between users and introduces inter-path interference (IPI), inter-symbol interference (ISI) and multi-path access interference...
