JDC performance versus condition number. The dimensions of ${\mathcal{C}}_N$ and the SNR value are set to N = 5, K = 15, and SNR=10 dB, respectively. Top: the average error $\alpha (\mathit{A},\tilde{\mathit{A}})$ evolution of all the algorithms as a function of the condition number of one of the diagonal matrices D^(k). Bottom: the average numerical complexities (left) and the CPU time (right) of all the algorithms, respectively.
