摘要
本文针对部分极化波情形,利用电磁波的Stokes矢量表示法研究了极化信号的优化接收问题;利用Lagrange乘子法,分别推导了以信号干扰功率差(PDSI)和信号干扰噪声比(SINR)作为优化目标函数时接收天线的全局最优极化;并通过数值实例验证了文中结论。
In this paper, the problem of optimal reception of partially polarized signals is investigated by means of Stokes vector description of EM waves. The receiving antenna's global optimal polarizations are derived using Lagrange multiplier method with SINR(Signal-to-Interference-and-Noise-Ratio) and PDSI(Power-Difference-between-Signal-and-Interference) as the objective functions respectively. At the end of this paper, results are verified by a numerical example.
