【摘要】：智能天线技术在铁路通信中的应用已经十分广泛,自适应波束形成是智能天线技术的重要问题之一。共轭梯度算法相较于传统的最陡下降法可以解决其收敛速度相对于矩阵特征值敏感的问题,可以加速收敛速度。本文采用共轭梯度算法,对于一个机车信号接收系统进行了仿真模拟,结果表明,共轭梯度算法可以快速准确的接收信号,提高铁路通信系统的可靠性和稳定性。
[Abstract]:Smart antenna technology has been widely used in railway communication. Adaptive beamforming is one of the most important problems in smart antenna technology. Compared with the traditional steepest descent method, the conjugate gradient algorithm can solve the problem that the convergence rate is sensitive to the eigenvalues of the matrix, and can accelerate the convergence rate. In this paper, the conjugate gradient algorithm is used to simulate a locomotive signal receiving system. The results show that the conjugate gradient algorithm can receive signals quickly and accurately, and improve the reliability and stability of railway communication system.
