Polyphonic musical instrument recognition based on a dynamic model of the spectral envelope
We propose a new method for detecting the musical instruments that are present in single-channel mixtures. Such a task is of interest for audio and multimedia content analysis and...

Likelihood-Based Algorithms for Linear Digital Modulation Classification in Fading Channels
Blind modulation classification (MC) is an intermediate step between signal detection and demodulation, with both military and civilian applications. MC is a challenging task, esp...

Constellation labeling maps for low error floors
A constellation labeling map is the assignment of a bit pattern to each symbol in a signal-set constellation. In a system with bit-interleaved coded-modulation and iterative decod...

Perfect Reconstruction AM-FM Image Models
For the first time, we present an AM-FM image model that, in addition to being remarkably consistent with human visual perception, also provides perfect reconstruction of the imag...
