Canonical time-frequency, time-scale, and frequency-scale representations of time-varying channels
Mobile communication channels are often modeled as linear time-varying filters or, equivalently, as time-frequency integral operators with finite support in time and frequency. Such a characterization inherently assumes the signals are narrowband and may not be appropriate for wideband signals. In this paper time-scale characterizations are examined that are useful in wideband time-varying chan...

متن کاملOptimal Quadratic Array Processing Using Time-Frequency and Time-Scale Representations
The use of sensor arrays in signal processing applications has received considerable attention, especially in radar/sonar processing. Sensor arrays are able to enhance desired signal reception while simultaneously suppressing undesired components through the use of directionality. The performance of traditional matched-eld beamformers is severely limited for many random signal models of interes...
متن کاملA Simulation Tool for Space-time Adaptive Processing in GPS
With the wide use of GPS, it becomes more and more important to improve the positioning accuracy. The GPS signal is very weak, and can be easily interfered. Space-time adaptive processing(STAP) can suppress the jamming not only in the temporal domain, but also in the spatial domain. STAP has now become a good candidates for jamming mitigation in GPS. In order to evaluate the performance of vari...
متن کاملA Time-Frequency approach for EEG signal segmentation
The record of human brain neural activities, namely electroencephalogram (EEG), is generally known as a non-stationary and nonlinear signal. In many applications, it is useful to divide the EEGs into segments within which the signals can be considered stationary. Combination of empirical mode decomposition (EMD) and Hilbert transform, called Hilbert-Huang transform (HHT), is a new and powerful ...
