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...
