  MUSIC algorithm: Number of tones

+ 0 like - 0 dislike
472 views

Hello everyone, 
I am currently investigating MUSIC and I know the algorithm relies on the  prior knowledge of the number of independent sources but I do not understand how to choose it.. Is there any rule of thumb or theory about it? 

Thank you by advance

You can try different values and use BIC to decide on a good one.
