空地通信信道模拟器的研究与设计

摘要

Air-ground communication channel simulation is one of the most important aspects of communicationsystem simulation. The envelope distribution and Doppler power spectrum of received signal are analyzed and thedesign patterns of static channel and mobile channel are presented in terms of path loss, channel delay, multi-pathfading and channel noise. The feasibility and rationality of proposed design scheme are certified through computersimulation.%空地通信信道仿真是通信系统仿真的一个重要方面.在研究接收信号包络分布和多普勒功率谱的基础上,综合分析路径损耗、信道时延、多径衰落和信道噪声对信道的影响,对静止信道和移动信道,分别提出了信道模拟器的设计方案,并通过计算机仿真验证了设计方案的可行性和合理性.
