Yanbo Xue · Kongzhi yu juece · 2006
A modified extended cyclic MUSIC(EC-MUSIC) algorithm based on real-valued decomposing technique is presented to reduce the computational complexity and high hardware cost.A high-dimensional matrix with center-hermitian property is constructed,which maps a complex matrix into a real one.The proposed algorithm has the signal-selective property,improves its performance,and achieves a substantial reduction of the computational complexity.This algorithm is applicable to communication products with minitype.The effectiveness of this method is verified by simulation results with different SNRs.
