Figure 5 shows the RMSE of the proposed method and MUSIC as a function of the SNR as long as the two sources are resolved with a probability equal to 1.
(Luce H, Hashiguchi H, Kantha L, Lawrence D, Tsuda T, Mixa T: On the performance of the range imaging technique using UAVs during the ShUREX 2015 campaign, submitted) provide a more detailed description of the results with the Capon method and MUSIC algorithm.
The signal phases { φ k ( t ) } k = 1 2 are independent and follow a uniform distribution in [0, 2π]. Figure 6 shows the probability of resolution of the proposed method and MUSIC as a function of the number of snapshots N. In this case the signal to noise ratio is fixed to 1 dB.

The usability of online music streaming services could be greatly improved by developing emotion-based access methods, and automatic music emotion recognition (MER) is the most quick and feasible way of achieving it.
The subspace method, MUSIC, appears not to work at all, and there is a simple explanation for this: the presence of a second interfering source has not been taken into account in any of the methods, and for MUSIC, this turns out to be a critical problem; indeed, the one source assumption leads to an incorrect noise subspace estimate.
Although there is no "official" order for teaching the notes, many method books and music teachers would say that the "best" ones to start with are (in order): E, D, C, F, G, B, A, and B flat, before moving to the lowest and higher notes.
We briefly recall the 1D conventional estimation methods: BF, Capon and MUSIC, in the general context of array processing.
The error locator polynomial method developed for channel coding has, moreover, been shown to be a discrete version of the annihilating filter used in sampling with a finite rate of innovation and the Prony method in spectral estimation; the Pisarenko and MUSIC methods are further improvements of the Prony method when additive noise is also considered.
These methods are generalizations of the traditional Capon and MUSIC methods to the 3D configuration.
