Adaptive Locally Optimum Processing for Interference Suppression fromCommunication and Undersea Surveillance Signals

摘要

The technical results contained in this report include: Formulas for optimumprocessing of complex samples when the sign als has known and unknown phase structure; Formulas for optimum processing of complex sample amplitude, phases, and symmetric phase-differences when the signal has known and unknown phase structure; Formulas for the optimum processing of the frequency domain representation of the signal samples when the signal is narrowband; explicit formulas for processing samples when the statics are modeled by either non-central or central mixture models for which the parameters are estimated or implicit; Processing gain over traditional processing bounds and estimates in terms of model parameters for the above algorithms when the statics are modeled by either non-central or central mixture models; Comparison of processing gain bounds and estimates with performance estimates obtained through simulations for
