A new method of estimating DOA based on training signal is proposed. The training signals of users are supposed to be mutually orthogonal and the magnitude of each signal is constant, that is 1. The mathematical deduction of the new algorithm leads to a simple estimating formula. Combined with T-shape antenna array , the new algorithm can estimate the DOA accurately and rapidly.
