Abstract

In this paper, an l2 norm constraint-based reduced-dimensional MUSIC (l2CRD-MUSIC) algorithm for joint angle and delay estimation (JADE) with automatic pair matching in multipath environment is proposed. By utilizing the l2 norm constraint on the steering vector, the quadratic optimization problem in JADE is decomposed into a one-dimensional (1D) search problem. Thus, angles can be first estimated by a 1D search. For each estimated angle, the matching delay is estimated by the root finding technique. The proposed algorithm has lower computational complexity than the 2D-MUSIC method, but achieves comparable performance with the 2D-MUSIC method. Furthermore, the estimated angles and delays are automatically paired together. Simulation results are presented to verify the effectiveness of the proposed algorithm.
