An improved DOA estimation method based on MUSIC and MSCS

According to the merits and demerits of MUSIC algorithm and MSCS algorithm, a new DOA estimation method is proposed. By analyzing MUSIC and MSCS, the new method balances the computational complexity and accuracy. The core idea of this method is: in different conditions, we adopt different algorithms (MUSIC or MSCS algorithm) to make best use of the advantages and bypass the disadvantages. The simulation results show the effectiveness of this approach is very well.
