摘要

本文以DVB-S2标准为参考,分析了自适应编码与调制(ACM)技术在超高频卫星通信中的应用。分析的重点是w波段通信链路,包括对极高频(EHF)链路接收信噪比(SNR)的DVB-S2 ACM阈值的优化。该仿真模型包含了w波段实际系统性能分析和优化中不可忽视的雨衰落和放大器非线性。1 2

On the optimization of DVB-S2 links in EHF bands
In this paper an analysis on the use of Adaptive Coding and Modulation (ACM) techniques for EHF satellite communications is presented with reference to the DVB-S2 standard. The analysis is focused on W-band communication links and includes an optimization of DVB-S2 ACM thresholds of the received Signal to Noise Ratio (SNR) for Extremely High Frequency (EHF) links. The simulation model includes rain fading and amplifier nonlinearities which can not be neglected for the performance analysis and optimization of real systems in W-band. 1 2
