Rapid prototyping library for adaptive signal processing applications

In this paper we present a library for the rapid prototyping of adaptive signal processing algorithms, architectures and applications. The library is hosted by the DSP simulation software SystemView and covers virtually the complete spectrum of linear, and non-linear adaptive algorithms currently in use in contemporary DSP and communications applications. The library can be easily used with real signals, with variable system wordlengths, sampling frequencies and so on. Therefore in this paper we discuss the design philosophy behind the library and overview the various algorithms and applications that are implemented. The paper shows an implementation of an adaptive multiuser CDMA receiver/decision feedback equaliser (DFE) as an example of the relevance and rapid development that is possible. Copies of the library and example files can be downloaded from the Web following the instructions in the paper.
