用计算机模拟研究系统和用计算机进行辅助设计,是方便、经济、富有成效的方法。这种方法可以缩短研制周期,并可以藉此建立新的系统或发展新的理论。本文介绍数字微波通信系统的计算机模拟方法。由于多径衰落的校正技术是实现数字微波通信系统的关键技术之一,因而本文将重点介绍衰落信道及抗衰落方法的模拟。为此而建立起来的系统数学模型,对于研究系统中的其他问题也是适用的。如对数据通信、散射通信以及卫星通信等,亦有参考价值。
Computer simulation of research systems and computer-aided design is a convenient, economical and productive approach. This approach can shorten the development cycle, and can take this to establish a new system or the development of new theories. This article describes the digital microwave communication system computer simulation method. Since the correction technology of multipath fading is one of the key technologies to realize digital microwave communication system, this article will focus on the simulation of fading channel and anti-fading method. The system mathematical model established for this purpose is also suitable for studying other problems in the system. Such as data communications, scattering communications and satellite communications, also have reference value.
