Perform CUDA-accelerated sparse FFT

This is a convenience function that creates a CUDA sparse FFT processor and performs the computation.

§Arguments

  • signal - Input signal
  • k - Expected sparsity (number of significant frequency components)
  • device_id - CUDA device ID (-1 for auto-select)
  • algorithm - Sparse FFT algorithm variant
  • window_function - Window function to apply before FFT

§Returns

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