— The variances of matched and sidelobe free mis-matched filter estimators are given for arbitrary coherent targets in the case of aperiodic transmission. It is shown that mismatched filtering is often better than matched filtering in terms of estimation accuracy. A search strategy for finding general transmission codes that minimize estimation error and satisfy constraints on code power and am...

This contribution deals with the design of an all digital multirate receiver with nonsynchronized IF sampling and digital timing correction, that can be used in software defined radios. By performing timing correction prior to matched filtering, the complexity of the matched filter is reduced, but at the expense of additional aliasing. Design parameters, yielding low degradations with respect t...

Filtering ABSTRACT Singular spectrum analysis (SSA) and filtering methods were employed to extract the spontaneous low frequency components from voxel time courses acquired with a single-shot, gradient echo EPI sequence, and determine the functional synchrony in the human hippocampus region in order to distinguish Alzheimer’s disease subjects from age-matched controls. Their performances were e...

Low level data processing functions, like FIR filtering, pattern recognition or correlation, where the parallel implementation is supported by architecture matched special purpose arithmetic; high throughput FPGA circuits easily outperform even the most advanced DSP processors. In this paper investigates a high-speed nonlinear Adaptive median filter implementation is presented. Then Adaptive Me...
