摘　　要：该系统主要是研究基于软件无线电思想的调制解调技术。在以TI公司的TMS320C6711数字信号处理器（DSP）为核心的软件无线电平台上实现FSK，QPSK，QAM等多种制式的调制解调功能，通过对主机中虚拟平台的操作，实现对调制解调制式的实时选择和数据测量的实时显示，并以QPSK为例进行了观察和分析。The system is mainly studying the technology of the modem based on the thought of software defined radio. We try to realize many kinds of functions of modulation and demodulation such as FSK, QPSK, QAM on the platform of software defined radio centring on the digital signal processor （DSP） of TMS320C6711 in the TI Company .By operating the suppositional platform in the host machine, we not only try to choose the proper the format of modulation and demodulation and measure the datum but also observe and analyse QPSK as an example.
