Han Ying · Journal of China Institute of Communications · 2005
An algorithm on the estimation of the direction of arrival with unknown number of signal sources is presented in this paper. Under condition of unknown number of signal sources, the new algorithm is combined LP or Pisarenko method with ASPECT to estimate the DOA with high resolution. The spurious peaks in DOAs with LP or Pisarenko method can be removed and the number of signal sources can be determined at the same time. The computational complexity is reduced and the DOA resolution is also improved in this algorithm. Computer simulation results approve the correctness and validity of this new algorithm.
