射频仿真系统中多机通信的差错控制技术

ERROR CONTROL TECHNIQUE IN COMMUNICATION BETWEEN COMPUTERS IN RADIO SIMULATION SYSTEM

本文介绍了在射频仿真系统中，对多机通信过程中可能出现的错误的检测和控制技术。根据本系统专用接口卡的特点，选择了方正校验和数据表决校验相结合的方法，对数据传输错误进行检测，为提高方正校验的检错能力，我们将１６位信息位平均分成了４组，分别进行校验，并利用计时和计数的方法，解决了数据丢失问题。

This article has described a technique for error detecting and controlling that may take place in communication between computers in radio simulation system.According to the characteristics of the interface card of this system, we have selected the error detecting and controlling method to detected the error in data communication which consist of four square proofread and data voting proofread. For improving the error detecting ability,we have divided the 16 message bit into 4 groups averagely and detected dividedly.With the method of recording time and number,we have resolved the problem of data losing.
