A nonlinear filtering approach to estimation and detection in mobile communications.

The paper develops an open-loop digital receiver suitable for operation with frequency flat-fading channels disturbed by fast-fading conditions and large carrier phase variations. The receiver consists of a bank of ?matched? stochastic nonlinear filters (NLFs) and a maximum a posteriori probability...
