一种提高短波数据通信性能的方法

摘要

短波通信设备作为远距离和复杂地形进行通信的主要手段,广泛应用于广播、军事等领域.在短波数据通信系统中,存在着通信速率低所导致的延时过大、数据源数据量大造成的数据丢失等问题.文中通过对各种延时因素进行分析,给出了一种提高短波通信性能的方法.该方法通过提高接口速率和以数据包为单位对延时进行估计,可以做到延时和丢弃数据包的可控,防止发生信道丢失数据的随机性,是一种低开销、易于实现的开环控制方法.%As the primary means of communication in Long-distance and complex terrain, shortwave communication e-quipments are widely used in broadcasting, military and other fields. In shortwave data communications system, there is long communication delay caused by the low communication rate, and data loss caused by large volumes of data in the source. This paper discusses a variety of delay factors, and presents a new method to improve the performance of shortwave communication. The method by improving the interface speed and estimating the delay in data-packet, can control the time delay and discarded packets, prevents the randomness of data loss in channels, and is a low cost, easy to implement, open Loop control method.
