DOA Estimation Using Iterative MUSIC Algorithm for CDMA Signals
Ann‐Chen Chang, Jui‐Chung Hung · IEICE Transactions on Communications · 2009
In conjunction with a first-order Taylor series approximation of the spatial scanning vector, this letter presents an iterative multiple signal classification (MUSIC) direction-of-arrival (DOA) estimation for code-division multiple access signals. This approach leads to a simple one-dimensional optimization problem to find each iterative optimal search grid. It can not only accurately estimate DOA, but also speed up the estimating process. Computer results demonstrate the effectiveness of the proposed algorithm.
