摘　　要：研究软件无线电中的通用调制解调器的设计方法。针对软件无线电调制解调器的性能要求,提出以可编程片上系统SoPC(System on a Programmable Chip)技术为核心,以坐标旋转数值计算CORDIC理论为基础的设计方法,实现SoPC系统的软硬件协同设计。结果表明,该系统具有结构简单、成本低等优点,并充分体现软件无线电的灵活性和开放性,满足实际应用需求。This paper focuses on the design method of general modulation and demodulation for SDR （software defined radio）.Combined with the performance requirements of SDR,a kind of modulation and demodulation is presented in detail,which is based on SoPC technology and CORDIC algorithm.Finally,the system achieves SoPC HW-SW（hardwaresoftware）co-design.The results indicate that this system has strong points such as simple structure and low cost,fuUy shows the flexibility and open characteristic of SDR,and meets practical application.
