Performs GPU-accelerated sparse FFT on a signal

This is a convenience function that creates a GPU sparse FFT processor with the specified backend and performs the computation.

§Arguments

  • signal - Input signal
  • k - Expected sparsity (number of significant frequency components)
  • backend - GPU backend to use
  • algorithm - Sparse FFT algorithm variant
  • window_function - Window function to apply before FFT

§Returns

  • Sparse FFT result containing frequency components, indices, and timing information
