摘要

我们考虑了多用户检测和天线阵列。对于多用户检测，我们使用去相关检测器。结果表明，该系统受强干扰的影响较小，且具有近远电阻。此外，还观察到去相关检测器不依赖于空间互相关。然而，在传统的检测器中，观察到空间互相关导致的性能下降。

Beamforming for the decorrelating detector in synchronous CDMA systems

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.
