Multi-user interference (MUI) severely degrades performance in wireless CDMA transmission. Due to the central limit theorem, such interference is usually (near) Gaussian distributed (Vembu and Viterbi, 1996; and Verdu, 1998). Recently, it has been shown that for frequency/time hopping CDMA with single-user demodulation/decoding at the receiver, one can intentionally create appropriate non-Gaussian...
This paper presents a novel generalised Multi-Carrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system invoking smart antennas for improving the achievable performance in the downlink, as well as employing multi-dimensional Sphere Packing (SP) modulation for increasing the achievable diversity product. In this contribution, the MC DS-CDMA transmitter considered employs multiple Antenna...
