基于椭圆参数的最优极化策略

Optimal Polarization Strategies Based on Pol-Ellipse Parameters

针对基于椭圆参数的干扰环境下极化球面上的优化接收信干噪比参量等式,分析了几种特殊情况下的解析解,提出了几种基于椭圆参数的极化优化策略,包括三步搜索比较策略TSSC。在仿真实验中,对多种优化策略进行了比较。结果表明,TSSC策略只需在三次局部最优计算后再进行比较就几乎达到了全局最优,并用蒙特.卡罗法作了验证。

Aiming at the optimal reception of SINR（signal to interference-and noise-ratio） based on the pol ellipse parameters in the presence of interference and noise, some analytic solutions in several special polarization schemes are presented. Several optimal strategies are proposed. An optimal polarization scheme called Three Steps＇ Searching and Comparing（TSSC） is suggested. The comparison among these optimal schemes is given. Simulation results show that TSSC scheme closely approaches the global optimum quickly and efficiently. This conclusion has been validated by many random experiments with the Montecarlo method.
