小波变换在智能天线波束形成技术中应用

内容简介：智能天线是当前研究热点之一，首先介绍了波束形成的基本原理，按照盲算法和非盲算法将现有的波束形成算法进行分类并比较了算法的性能；其次，比较了基于小波变换和基于小波包的自适应波束形成算法，分析了基于小波变换的多分辨信号波达方向和基于小波神经网络的波束形成算法；最后，针对小波变换可在选择最优基方面和结合盲自适应算法进行联合分析方面进行了展望。

Abstract： Smart antenna is a current research focus. Basic principle of beam forming is introduced. The existing beam form?ing algorithms are classified and their performances are compared in accordance with the bind algorithm and non?blind algo?rithm. The adaptive beamforming algorithm based on wavelet transform and wavelet package is compared. Multi?resolution signal based on wavelet transform and beam forming algorithm based on wavelets neural network is analyzed. The prospect of the wave?let transform in optimal basis selection and the conjoint analysis with blind adaptive algorithm are looked forward.
