Performance comparison of reconstruction algorithm based on non-uniform sampling system

For sparse ultra-wideband signals in frequency domain, the non-uniform adoption system is used to sample the signals at different rates. OMP algorithm, LASSO algorithm and BCS algorithm are used to recover the non-uniformly sampled signal. According to the analysis and comparison of the simulation results, the following conclusions are drawn: BSC algorithm has little change in time-consuming and robustness with the increase of the number of observations, and has better reconstruction performance when the number of observations is low and the noise is included.
