Improved Beamspace ESPRIT-based DOA estimation via pseudo-noise resampling

Beamspace ESPRIT with pseudo-noise resampling is proposed which has improved performance as compared to original Beamspace ESPRIT. The resampling of Beamspace ESPRIT via pseudo-randomly generated noise is used to form estimator bank. Censored selection of the results of pseudo-randomly resampled Beamspace ESPRIT estimators is exploited based on the local performance test and reliability test.
