摘要
以TI公司的数字信号处理器(DSP)TMS320VC5416为CPU,设计了CDMA通信系统中反向链路信号处理过程的实验系统。CDMA反向链路信号处理过程比较复杂,不易观察。而利用DSP高速和精确的运算能力﹑丰富的通用输入输出口(需要配置)和其软件开发平台CCS中丰富的显示信号特征的功能,实验者能够多角度的观察和研究信号处理结果。给出了硬件电路设计和作为例子的多角度观察OQPSK调制。
The experiment system of signal processing in the revise link of CDMA communication system is designed with the digital signal processor TMS320VC5416 of TI corporation as the CPU. The signal processing is complex in the revise link in the revise link of CDMA communication system, so the processes are some difficult to be observed. However the experimenters can observe the resuits of processing by rapid and precise operational capacity and the many general input and output ports（be configured） of DSP and rich display characteristics of Code Composer System. The design of the circuit and the QPSK modulation as a example are given.
