Estimation algorithm for real-valued direction of arrival based on modified propagator method
Pingyuan Liang · Journal of Computer Applications · 2013
The real-valued modified propagator method was proposed to solve the large computational load problem of modified propagator direction of arrival estimation method.This proposed method employed the unitary transformation to rearrange the propagator to be real matrix,which decreased the computational load through the real-valued spectrum peak scanning.And it remained the same estimation performance with modified propagator method.At last,the simulation results confirm that the proposed algorithm can achieve superior estimation precision with lower computational load,compared with modified propagator method,propagator method and multiple signal classification method.
