Development of a General C++ Class for Wavelet Analysis
This project aims to develop an independent modulus for the wavelet analysis that contains a simple program interface and can be used flexibly.
The implementation was in C++ in the form of a wavelet analysis class and a signal queue. Features:
The Input/Output data format can be chosen at run time. The Input and the Output are separately configurable.
There are several possibilities for choosing the array and distribution of the frequency bin. The frequency bin vector can also be transferred.
Seven wavelets are implemented.
A down-sampling method can be used for the acceleration (factor: 1.2 convert frequency bins are chosen automatically).
Because of the disjunction in signal queue and analysis, an asynchrony Input/Output is possible.
Compiling an optimized numerical library can be achieved. Currently, the application of the "Intel® Signal Processing Library" (SPL) or of the "Intel® Integrated Performance Primitives" (IPP) is possible.
The signal queue class can be used independently of the analysis class. It also implements the down-sampling function.
The developed classes are used as a modulus in the acoustic measurement and analysis system PAK. The analysis class was also integrated as a signal processing atom WLLIB in STx.
