JDC performance versus sweeps. The average value of the cost function evolution of all the algorithms as a function of the number of sweeps with various SNR levels. The dimensions of ${\mathcal{C}}_N$ are set to N = 5 and K = 15. The SNR values are set to 25 dB (a), 10 dB (b), and -5 dB (c), respectively.
