Figure 2From: An efficient joint estimation of wideband polynomial-phase signal parameters and direction-of-arrival in sensor arrayEstimation RMSE for θ , a 2 and a 3 ( K = 3). Left column: variable SNR, N = 257, M = 100. Middle column: variable M, N = 257, SNR = 10 dB. Right column: variable N, SNR = 10 dB, M = 100.Back to article page
