A computationally efficient symmetry-compressed beamspace MUSIC algorithm
A low-complexity symmetry-compressed beamspace MUSIC (SC-BS-MUSIC) algorithm is proposed based on the compressed spectrum theory. Since the beamspace transformation matrix is a real-valued matrix such that the beamspace steering vectors of symmetric angles are conjugate symmetric. Therefore, the range of spatial spectrum search required for SC-BS-MUSIC is halved, which greatly reduces the computational complexity.
