Blind Equalization and Multiuser Detection in Dispersive CDMA Channels
Xiaodong Wang and H. Vincent Poor, Fellow, IEEE
Abstract― The problem of blind demodulation of multiuser information symbols in a high-rate code-division multiple-access (CDMA) network in the presence of both multiple-access interference (MAI) and intersymbol interference (ISI) is considered. The dispersive CDMA channel is rst cast into a multipleinput multiple-output (MIMO) signal model framework. By applying the theory of blind MIMO channel identication and equalization, it is then shown that under certain conditions the multiuser information symbols can be recovered without any prior knowledge of the channel or the users’ signature waveforms (incl……
