Abstract

Abstract

The uniform circular array is transformed into uniform linear array by the spatial matched filter transformation from element space to beam space. Based on the space-time matched filter output in frequency domain, the joint angle and delay estimation with uniform circular array in aperiodic spreading system is solved with DOA matrix method. The joint estimation algorithm also solved the problem, that the multipath number can not be larger than the element number in conventional spatial processing method. The theoretical analysis and computer simulations demonstrate that the method is an unbiased estimator and its estimation precision is superior to that of the sliding correlator.
