An optimized MUSIC (MUtilple SIgnal Classification) is proposed, basing on Simplex search method. It can largely improve the scan speed of conventional and avoid singularity Hessian matrix gradient based optimization methods. also provides possibility to distinguish coherent signal with acceptable time cost, in this case, we proposed an enumeration coherence solver. Both simulations experiments are carried out for RF localization purposes. The results shows that methods has faster computational same numerical precision as method does, which confirms feasibility
