关于美国加州工业大学黄华国教授2次学术报告的通知

发布日期 :2010-11-02    阅读次数 :2999

报告题目:1. Antenna Beam Design using Minimax Algorithm

              Abstract

Minimax Algorithm minimizes the maximum cost of the performance function. This algorithm can be used in many engineering applications such as curve fitting, filter design and antenna beam pattern design. This presentation discusses the antenna pattern design with phase array antenna. Performance parameters such as the step size, relative weight of the cost function to the antenna pattern will be discussed.

            2. Direction of Arrival Estimation using ESPRIT Algorithm

          Abstract

             Define the direction of arrival (DOA) of signal source using the conventional antenna subject to the limitation of the antenna mainlobe beamwidth (MLBW). Several high resolution algorithms using the model based or eigenanalysis approaches were presented by many authors. This presentation discusses the one of the generalized eigen-analysis method ESPRIT (estimate signal parameters via rotational invariant technique). Performance analysis based on Matlab simulation will be presented.
