A spectral estimation toolkit for Java applications

This paper examines the capability, performance, and relevance of a high-performance advanced signal processing toolkit in Java, a programming language for Web-based applications. To demonstrate the simplicity, ease, and application use of the toolkit, a spectral estimation applet has been developed in the Java environment using advanced Internet technologies such as Remote Method Invocation (RMI). This application provides an interactive and visual approach in understanding theoretical concepts of advanced signal processing methods and shows the need to create more application applets to better understand additional concepts in signal and image processing. Furthermore, a toolkit with limited functionality and different framework has been developed for embedded and handheld devices such as cellular phones and palm pilots. This toolkit is also shown to be useful in developing applications MIDlets on those devices.
