modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
countless applications. Here, at the Georgia Institute of Technology, one of such
teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part
of the Georgia Center for Advanced Telecommunications Technology (GCATT).
The purpose of this report is to provide Matlab code to simulate the basic processing
involved in the generation and reception of an OFDM signal in a physical
channel and to provide a description of each of the steps involved. For this purpose,
we shall use, as an example, one of the proposed OFDM signals of the Digital
Video Broadcasting (DVB) standard for the European terrestrial digital television

Description: 本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的
方向图，采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化，
通过C++语言编程计算实现，从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合，达到设计
要求。全局优化是本文的特色，它弥补了局部优化结果的精确度依赖于初始值的缺点，因而得以保证通过优
化得到的天线主波束与给定波束的主瓣相吻合，副瓣也得到有效控制。该方法具有快速收敛，计算量小等优
点，是一种解决阵列天线波束赋形问题的有效方法。 -In this paper, the amplitude and phase weighted array antennas for global optimization method. Order to make the antenna radiation beam to form a given pattern, using the combination of DFP and BFGS formula variable metric algorithm to optimize the amplitude and phase distribution of each cell of the array antenna feed, calculated through C++ language programming to achieve, which makes optimization array antenna main beam shape is consistent with the pre-to the beam shape to meet the design requirements. Global optimization is a feature of this article, it makes up for the shortcomings of the accuracy of the local optimization results depend on the initial value, and thus can be guaranteed through the optimization of the antenna main beam to coincide with the main lobe of a given beam, sidelobes also been effectively controlled . The method has fast convergence of computing and small volume, is a solution to the array antenna beamforming. Platform: |
