Radio technologies have undergone increasingly rapid evolutionary changes in the recent past. The first cellular phones used narrow-band FM modulation, which was soon replaced by digital modulation in second & third generation devices. Today, multiple-antenna systems are being employed to increase data rates. These provide improved quality while decreasing operational costs.

测试无疑是无线产品开发中的一个必不可少的步骤，但要想在现场测试和实验室测试之间找到正确的平衡点却并非易事。现场测试计划根本无法捕捉产品在实际运行中遭遇的多种条件，但要想在实验室中创建出真实的无线电信道环境，大量的时间和技能往往也是不可或缺的。随着5G无线电技术的引入，这两种方法只会变得越来越复杂。

Vertex® Baseband Synchronizer

3GPP的最新发展提出了对卫星通信中衰减条件进行测试的必要性，因为5G NTN（非地面网络）将会把卫星组件引入传统的地面移动蜂窝5G系统中。题为“关于新型无线电（NR）支持非地面网络的研究”的3GPP规格TR 38.811详细定义了用于大规模参数的多种信道模型，例如阴影投射、室外至室内（O2I）损失、杂乱损失、路径损失，以及具体适用于卫星应用的多种小规模参数。尽管这些模型代表的是对无线电传播的最佳理解，但也会带来一系列涉及卫星接收机性能的全新挑战，而我们也需要以条理清晰的方式对两项应用中最关键的参数进行检测。

为了实现最佳的结果，而不是简单地根据3GPP的规格进行信道模型仿真，我们更应当考虑是哪些因素可能导致卫星接收机失败，并且找出可以在实验室中对这些参数开展压力测试的模型。欢迎阅读本白皮书，并了解如何为系统性的卫星通信测试开发一个建立测试矩阵的基础，并根据所需的NTN应用对其加以进一步完善。

Recent developments in 3GPP require testing satellite communication conditions for interworking with 5G cellular networks. This brings a new set of challenges for satellite transceiver performance that must be examined methodically
