双DSP在数字通信终端中的应用

Application of Two DSPs on the Terminal Technologies in TDMA Mobile Communication System

在数字信号处理器 ( DSP)应用的背景下 ,提出了一种实现时分多址移动通信的新方案。本文根据系统的特点采用双微处理器分别作为时分终端和业务终端的控制器 ,实现了语音、低速率数据的多业务接入 ,使之成为具有多业务通信能力的较完备的时分双工移动通信系统的端机设备。

In this paper,a new design is built under the application of DSP,which can realize the time-division terminal and the service access terminal of the base and mobile station.The new system is composed of two digital signal processors and some additional circuits.One of the DSP chips undertakes the function of service access, while the other does the function of channel transmission and central controlling.
