时间分集（TD）作为高频广播卫星应用的一种有前途和成本效益的解决方案，最近引起了人们的注意。目前的工作提出了一个通用的预测模型，通过近似的时间动态雨衰减的联合对数正态分布的TD的应用。所提出的方法进行了测试，对实验数据和其性能的卫星链路的基本参数进行了研究。
Time diversity (TD) has recently attracted attention as a promising and cost-efficient solution for high-frequency broadcast satellite applications. The present work proposes a general prediction model for the application of TD by approximating the time dynamics of rain attenuation through the use of the joint lognormal distribution. The proposed method is tested against experimental data and its performance is investigated with respect to the basic parameters of a satellite link.
