I am implementing QSS based signal considering 10 no of sensors, 5 frames and every frame consist of 512 QSS signals. after performing processing i get Co-variance matrix R as shown in the attachment of dimension 10by10 and 100by1 after applying Vec function. where Y is the final matrix. after applying SVD on Y it give me 100by100 noise space vector. I want to apply MUSIC but i couldnt able to generate AB(as shown in attachment at the end) of Dim 100by 1081(where 1081 can be generated by range=-90:0.1:90). How i can generate AB using Vec or Khatri Rao based method???
