一种新型的恒模自适应阵列初始化方法

智能天线在移动通信中的应用已经引起了广泛的关注．恒模阵列能够形成自适应波束，但其初始权矢量的选取影响着对所需信号的捕获性能．该文提出一种在信号到达方向(DOA)已知的情况下，基于泰勒(Taylor)阵列的恒模阵列权值初始化新方法．仿真结果表明，这种新方法不仅能解决抗干扰问题，还可加快恒模算法的收敛速度．

A New Algorithm for Initialization of Adaptive Array with Constant Modulus

Applications of smart antenna in mobile communications have received enormous worldwide interest in recent years. A CMA array can form an adaptive beam. However its capability of capturing desired signals is influenced by its initial weight. In this paper, we present a new initialization method based on Taylor arrays for CMA arrays with the direction of arrival (DOA) of the desired signal available. Simulation results show that the new method not only can resolve the problem of interference, but also can speed the CMA convergence.
