Abstract In recent years, estimation in cumulant domains was studied mainly in the aspect of asymptotic performance, including asymptotic unbiased estimation and asymptotic covariance. Unbiased estimation performance for finite snapshots is discussed in this paper. Simulation results demonstrate that performance of DOA unbiased estimation is better than that of biased for low SNR.
