Digital Signal Processing Laboratory

The Digital Signal Processing (DSP) Laboratory at Florida International University was established in August 1994, with the two-fold purpose of developing research work in various areas of DSP, while providing our graduate and undergraduate students with an opportunity to experience DSP research and learn the specific skills sought by industrial employers in this field.

The DSP Laboratory has developed and implemented algorithms for the processing of signals in diverse contexts. Several of our projects have involved processing signals from biomedical transducers, such as Blood Volume Pulse photoplethysmographs, and Electroencephalogram (EEG) and Electromyogram (EMG) electrodes.

We have applied processing to the signals from these transducers towards the development of alternate human-computer interfaces for the benefit of users with severe motor disabilities. Recently, we have worked in integra ting an infrared video eye gaze tracking system with the EMG-driven interface.

The DSP Lab has carried out research in the area of Deconvolution of the Doppler-Azimuth Radar Spectrum, by which the spatio-temporal data obtained from a multi-element radar array is enhanced to obtain a more defined characterization of objects of interest, while minimizing the effects of unwanted components.

The DSP Lab has also been involved in applied research for the local manufacturing industry. We have developed a self-tuning motion control system for a local Computerized Numerical Control (CNC) company. In this project, a DSP chip executes an algorithm to obtain a dynamic model of a CNC machine (such as a lathe or milling machine). It is then possible to implement a real-time inverse controller to compensate for the dynamic characteristics of the plant, yielding improved performance.
The website is developed by the Digital Signal Processing Laboratory team and is directed by Dr. Armando Barreto. The aim of the website is to provide information about the DSP Lab, DSP Crew, Publications, and various research projects.
