Cyclic Cross-correlation based Two-dimensional Direction of Arrival Estimation Algorithm

摘要：

Many modulated communication signals exhibit a cyclostationarity property,corresponding to the underlying periodicity arising from carrier frequencies or baud rates.By exploiting cyclostationarity,the direction-of-arrival (DOA) estimation can be significantly improved.In this paper,we propose a new two-dimensional (2-D)DOA estimation method that exploits cyclostationarity to enhance the noise suppressing effect.The proposed method is based on the cyclic cross- correlations of sensor outputs and is asymptotically exact for both narrowband and wideband sources.In addition,the new method does not require any 2-D search or pair matching for 2-D DOA estimation problems.Theoretical analysis and computer simulation simultaneously indicate that the proposed method has a better performance in noise suppressing and signal selectivity.
