Instantaneous Spectrum Estimation of Event-Based Densities

We present a method for obtaining a time-varying spectrum that is particularly suited when the data are in event-based form. This form arises in many areas of science and engineering, and especially in astronomy, where one has photon counting detectors. The method presented consists of three procedures. First, estimating the density using the kernel method; second, highpass filtering the manife...

MIMO instantaneous blind identification based on second-order temporal structure

Blind identification is a crucial subtask in signal processing problems such as blind signal separation (BSS) and direction-of-arrival (DOA) estimation. This paper presents a procedure for multiple-input multiple-output instantaneous blind identification based on second-order temporal properties of the signals, such as coloredness and nonstationarity. The procedure consists of two stages. First...

An Algorithm of Digital Modulation Identification Based on Instantaneous Features

Automatic modulation identification plays an important role in non-cooperative communication systems. An improved approach, based on instantaneous features and binary tree classifier has been proposed for the classification of Medium Frequency (IF) digital signals at low signal-to-noise ratio (SNR) situation. Mean filter was applied to suppress the noise and five new characteristic parameters s...

A Low Bandwidth Speech Coder Based on the Ratio Spectrum

We have implemented a low bandwidth speech coder using a new spectral representation called the ratio spectrum. The ratio spectrum is approximated in the digital domain by the normalized cumulative sum of the magnitude of the Fourier spectrum. This cumulative sum is guaranteed to be a monotonic nondecreasing function between zero and one. For each frame, frequency values are extracted by unifor...
