Abstract :
The 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. A blind minimum-mean-square-error (MMSE) detector is built based on the theory of blind MIMO channel identification and equalization. This detector only needs the desired user´s signature waveform. It is capable of suppressing both MAI and ISI
