摘要
实时嵌入式自适应波束形成在现代无线通信系统中具有广泛应用,也是"阵列信号处理"课程教学的难点和重点内容。本文以最小方差无失真响应(MVDR)波束形成器等为例,详细介绍了基于凸优化工具箱CVXGEN的实时嵌入式自适应波束形成器设计过程,并分析了其计算时间和波束形成性能。实践表明,将CVXGEN引入到实验教学中,可使实时嵌入式自适应波束形成器的设计过程更加直观和易于理解。
Real-time embedded adaptive beamforming has been widely used in modern wireless communication systems, and meanwhile, it may also be one of the difficult and important contents in the teaching of Array Signal Processing course. This paper takes the minimum variance distortionless response （MVDR） beamformer and other adaptive beamformers as examples, and introduces the application of the convex optimization toolbox of CVXGEN in the design of real-time embedded adaptive beamformers. The calculation time and performance of the real-time embedded beamformers are analyzed. It is indicated that the design process of real-time embedded adaptive beamformer can be more intuitively and easily understood by introducing the CVXGEN toolbox into practice teaching.
