I have a linear 4 element antenna array currently in my design, I am able to obtain the I/Q data from each antenna. Now I am trying to implement the MUSIC algorithm to obtain the AoA (Angle of Arrival). I have read some articles about the algorithm, however, I did not come across any article that explains how theory can be implemented in practice. I have few question hope some one will support me.
Are there any tutorials or articles that describes the MUSIC algorithm implementation detail? I prefer in C/C++ language. But any other language is also ok.
In the derivation of the MUSIC algorithm, normally it assumes N number of sources. Is this the number of actual sources or does it also counts multipath signals?
Are there any articles describing MUSIC algorithm implementation once we have the I/Q data?
Thanks a lot!!
