Figure 6

The RMSE of the compared algorithms versus SNR. The RMSE is defined by the formulaRMSE= 1 K k = 1 K 1 Mon mon = 1 Mon ( θ ̂ k , mon θ k ) 2 , where Mon is the number of Monte-Carlo simulations, θ ̂ k , mon is the k th DOA estimated value of the month simulation. The settings are: θ 1 = 10°, θ 2 = 30°, N = 10 sensors, T = 1,200 time snapshots. The number of Monte-Carlo simulations is Mon = 500.
