Alpha稳定分布噪声下级联恒模阵列及其稳定性分析

A Robust Cascade Constant Modulus Array in Alpha-Stable Noise Environment and Its Steady-State Analysis

该文研究Alpha稳定分布噪声下级联韧性恒模阵列的稳定性。首先,提出一种新型的信号对消器,把本级阵列捕获的信号从接收数据中消除,并分析了该对消器达到的稳定状态。然后,以韧性的波束形成器和新型的信号对消器组成级联恒模阵列。分析了恒模信号和Alpha稳定分布噪声在级联恒模阵列间的传递情况。数值仿真验证了理论分析的结论,并对级联恒模阵列的多信号恢复进行了模拟。

This paper studies the steady-state of a robust cascade constant modulus（CM） array in alpha-stable distribution noise environment. A new signal canceller is proposed to cancel the captured signal by the previous beamformer. The convergence behavior of the canceller weight vector is examined. The behaviors of signals and alpha-stable noise transmitting along the cascade CM array are investigated. Computer simulations are presented to support this theoretical analysis.
