摘要

在当今的蜂窝网络中，自适应智能天线起着重要的作用。期望的波束形成可以通过将主波束指向用户和零波束指向干扰来实现。本文将泄漏最小均方(LLMS)和变步长泄漏最小均方(VSLLMS)用于智能天线的自适应波束形成。基于不同信噪比下产生的主波束方向精度、零方向精度、最大旁瓣电平(SLLmax)精度和收敛速率，对两种算法进行了比较研究。

Beamforming in Smart Antenna with Multiple Interferers using Leaky LMS and Variable Step Size Leaky LMS

In today’s cellular network, adaptive smart antenna plays an important role. Desired beamforming can be achieved by directing main beam toward user and null toward interferer. In this paper, leaky least mean square (LLMS) and variable step size leaky least mean square (VSLLMS) are used for adaptive beamforming in smart antenna. A comparative study between the algorithms is done based on accuracy of produced main beam direction, null direction, maximum side lobe level (SLLmax) and rate of convergence for different SNR.
