The pre-processing method based on signal conjugate cyclostationary
Hui Chen, Wang Yong-liang, Wang Bu-hong · 2004
In this paper we propose a kind of pre-processing method of conjugate cyclic correlation. These methods make use of the information of the matrix of conjugate cyclic correlation is Hankel matrix. Under the condition of low signal-noise ratio (SNR), these pre-processing methods can improve the performance of direction-of-arrival (DOA). Its effectiveness is illustrated by the simulation results.
