本文提出一种用数字方法处理多频信号的新算法,并介绍了这种算法硬件实现的概况。实验表明,高效率的算法与高效率的硬件设计相结合,使得用数字处理方法实现的多频信号收发系统在成本价格、体积、功耗、性能各方面都优于其它方法实现的系统。实验系统是可编程控制的,一套硬件既可以处理前向信号,又可以处理后向信号。测试表明,各项指标均已满足GB3971.3—83国标中的有关要求。实验系统是多路复用的,平均每路使用集成电路11片,大部分为74系列中规模电路和8位微处理器及其外围芯片,超大规模集成电路的用量每路平均不到0.2片。
In this paper, we propose a new algorithm to process multi-frequency signals by digital method and introduce the hardware implementation of this algorithm. Experiments show that the combination of high efficiency algorithm and high efficiency hardware design makes the multi-frequency signal transceiver system realized by digital processing method better than other methods in terms of cost, volume, power consumption and performance. Experimental system is programmable control, a set of hardware can handle the forward signal, but also can handle the backward signal. Test shows that all the indicators have been GB3971.3-83 GB in the relevant requirements. The experimental system is multiplexed, with an average of 11 integrated circuits per channel, most of which are 74-series medium-scale circuits and 8-bit microprocessors and their peripheral chips. The usage of VLSI averages less than 0.2 per channel .
