Figure 7From: A novel method for sparse channel estimation using super-resolution dictionaryMSE performance in different SNR environments. The compressed sensing methods can increase their performance significantly by using dictionaries with a finer resolution (for OMP, λ=2,4); OMP_DFT, OMP_OPT, and OMP_DIC represent Fourier basis, iterative optimize basis, and dictionary used in OMP algorithm, respectively.Back to article page
