Fast Algorithm for Real Signal Sparse Decomposition Based on FHT

  • Received Date: 20 Dec 2007
  • Publish Date: 18 Feb 2009
  • A new signal sparse decomposition approach was proposed for easy software implementation.This algorithm converts very time-consuming inner-products in sparse decomposition into cross-correlations,so that the speed of sparse decomposition is increased greatly.For real signals,cross-correlations are done by fast Hartley transform(FHT).Simulation results verified the effectiveness of the proposed algorithm.
