Downlink DS-CDMA Transmission with Joint MMSE Equalization and ICI Cancellation
— The bit error rate (BER) performance of downlink DS-CDMA in a frequency-selective fading channel can be significantly improved by the use of frequency-domain equalization (FDE)...

Successive Interference Cancellation in Clipped and Product Combining aided FFH Multi-User Systems
— In this contribution, we propose two successive interference cancellation (SIC) schemes for a fast frequency hopping (FFH) multiple access (MA) system using M-ary frequency shi...

Chip-interleaved Multi-rate CDMA with 2-dimensional OVSF Spreading
—Chip interleaving technique has been proposed for DS-CDMA to eliminate the multiple-access interference (MAI). In this paper, we develop this technique to provide the single- or...
