Matlab program for 3D DOA estimation of L-shaped array based on augmented matrix pencil
no vote
In the spatial DOA estimation, the array element arrangement of the surface type is needed. This program is set as the L-shape distribution of 8 + 8 microphone, and the DOA estimation can be recovered by using the geometric relationship

DOA estimation of music algorithm signal based on microphone array signal
no vote
The covariance matrix of the output data of any array is eigendecomposed to obtain the signal subspace corresponding to the signal component and the noise subspace orthogonal to the signal component. Then, the orthogonality of the two subspaces is used to estimate the parameters of the signal. Ideally, the data subspace and the noise subspace are orthogonal. The number of array elements used in this code is 12, the distance between elements is 0.5m, the signal-to-noise ratio is 40, two source signals are recovered by music algorithm.

Compressed sensing signal reconstruction algorithm
no vote
After the compressed sensing, signal to be restored to the original signal, at this time we are going to reconstruct the compressed signals to recover. Signal reconstruction for restoration of effectiveness, we also will be analyzed through variance error. This code to a series of traditional reconstruction algorithm analysis. Hope I can help you!

Study on DOA tracking source cross, angle resoluti
no vote
Signal DOA estimation, usually involves the source signal paths crossed, or angle resolution of signal resolution is not high, in this case, compressed sensing based DOA estimation how to deal with it? For relocations and preprocessing of source signals, enhanced signal to noise ratio.
