Recursive structures and finite impulse response implementations of linear multiuser detectors for an asynchronous CDMA system.

Recursive structures and finite impulse response implementations of linear multiuser detectors for an asynchronous CDMA system.

We present order-recursive structures for implementing the linear decorrelating and linear minimum mean square error (MMSE) detectors in a computationally efficient manner. These infinite memory length, linear time invariant, noncausal systems can be approximated by implementing them as K-input K-ou...
