This study presents an optimized B-spline redundant wavelet transform (RWT) for Digital Signal Processors (DSPs). The new method significantly enhances execution speed for analyzing non-stationary signals and singularities.

Area of Science:

  • Signal Processing
  • Numerical Analysis
  • Computer Engineering

Background:

  • Non-stationary signals require advanced analysis techniques.
  • Singularity detection and characterization are crucial in signal processing.
  • Efficient implementation of transforms on Digital Signal Processors (DSPs) is essential for real-time applications.

Purpose of the Study:

  • To develop an optimized method for implementing a B-spline based redundant wavelet transform (RWT) on a Digital Signal Processor (DSP).
  • To provide exact operation counts for the RWT at any integer scale and B-spline order.
  • To evaluate the performance improvement of the optimized RWT method.

Main Methods:

  • Derivation of exact operation count expressions for B-spline based RWT at integer scales.
