Abstract :
We consider both multiuser detection and antenna arrays. For the multiuser detection, we use the decorrelating detector. It is shown that the resulting system is less affected by strong interferences and has the near-far resistance. Furthermore, it is observed that the decorrelating detector does not depend on the spatial cross-correlation. In the conventional detector, however, the performance degradation from the spatial cross-correlation is observed
