Decorrelating detectors were proposed as tools to combat the near-far problem in multi-user CDMA communication systems. They were also used as the first stage of many two-stage, multi-user signal separators to facilitate tentative decisions for the canceller stage. These decorrelators completely separate signals, but with relatively high additive noise. Different separators, which may not totally reject other signals, have been shown to result in better error probability with any value of interference energies. These separators can be implemented with an adaptive algorithm, termed “Bootstrap”, which can easily be used in situations where the cross-correlation matrix is unknown or the codes have been altered by the channel. |
