JDC performance versus SNR. The dimensions of ${\mathcal{C}}_N$ are set to N = 5 and K = 15. Top: the average error $\alpha (\mathit{A},\tilde{\mathit{A}})$ evolution of all the algorithms as a function of SNR. Bottom: the average numerical complexities (left) and the CPU time (right) of all the algorithms, respectively.
