“…The length of the Gaussian window used in this study is 63 with σ = 1 and ∆ f = 2. Let us compare the proposed algorithm with the conventional TF-MUSIC algorithm, the ADTFD based ridge tracking algorithm [25], and spatial adaptive TFD based Viterbi algorithm [24], for the signal to noise ratios (SNR) ranging from −10 dB to 10 dB, using the mean square error (MSE) as a criterion. The MSE between the original angle, i.e., θ and estimated angle, i.e.,θ is computed as:…”
