Song, Rongfang, Guoan Bi, Guangguo · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2001
Quadratic programming models for integrated space-time interference suppression in CDMA systems are proposed in this paper. The models integrate the advantages of smart antenna and RAKE receiver, mitigate multiuser access interference (MAI) and interchip interference (ICI),and combine multipath components. The zero-forcing conditions are derived. Neural network implementation of the models is also studied.
