Reconstruction Technique of Non-Uniform Sampling System Based on OMP Algorithm

Aiming at ultra-wideband signal with sparse frequency domain, an ultra-wideband signal reconstruction technique based on compressed sensing non-uniform sampling system is proposed, solving the problem that not only the traditional sampling theorem causes the sampling frequency too large which resulting in the waste of resources, but also the development of hardware equipment can not be satisfied in the short term. This letter introduces a non-uniform sampling structure, under-sampling the ultra-wideband signal sparse in the frequency domain, and then recover the signal is by using the OMP reconstruction algorithm. This method putting forward in this paper can effectively solve the problem of too large sampling frequency, low reconstruction efficiency and unrealizable hardware equipment.
