NTN TDL 信道 [1] 和地面 TDL 信道之间的主要区别是: NTN TDL 信道除了由于移动或用户设备 (UE) 运动导致的多普勒频移外,还考虑了卫星运动引起的多普勒频移。 NTN TDL信道延时曲线与地面TDL信道断面不同,因为传播延迟大,散射环境不同。 按照以下步骤对 3GPP TR 38.811 第 6.9.2 节中规定的 NTN 频率选择性...
一、前言 此示例说明如何对两种类型的新空口 (NR) 非地面网络 (NTN) 信道进行建模:平坦衰落窄带信道和频率选择性衰落抽头延迟线 (TDL) 信道。这些信道用于模拟不同的NTN部署场景,涵盖地球同步轨道(GSO)卫星和非地球同步轨道(NGSO)卫星。在此示例中,将通过对从基本信道模型生成的路径增益应用由于卫星移动而…阅读全...
NTN link by evaluating the throughput of NR Physical Downlink Shared Channel (PDSCH) in an NTN channel, specifically, the tapped delay line (TDL) NTN channel. We will also learn about the different Doppler compensation strategies employed in an NTN link. We will also briefly talk about ...
