本文着重讨论微处理机在突发无线电通信系统中的应用问题。文中介绍了一种采用扩展频谱调制技术并应用声表面波匹配滤波器实现快速同步的无线电突发通信系统模型。作为系统实验,本文具体讨论了一种采用Z-80系列微处理机控制的突发通信系统的软件设计,给出了收发设备与微处理机的接口电路。实验系统的性能为:在带宽为200～300千赫的超短波信通上,传输一份100字的中文电报(由400个数字符号组成)的时间不超过130毫秒；在+5dB的信噪比条件下工作,实测符号错误概率为2×10~(-4)。
This article focuses on the application of microprocessors in a burst radio communication system. In this paper, a radio burst communication system model based on spread spectrum modulation and SAW matched filter is introduced. As a systematic experiment, this paper discusses in detail the software design of a burst communication system controlled by the Z-80 series microprocessor, and gives the interface circuit between the transceiver and the microprocessor. The performance of the experimental system is: transmitting a 100-character Chinese telegram (consisting of 400 digital symbols) for no more than 130 milliseconds in ultra-shortwave communications with a bandwidth of 200 to 300 kHz; at a signal-to-noise ratio of +5 dB Working conditions, the measured symbol error probability of 2 × 10 ~ (-4).
