摘　　要：基于VHDL与MAX+PLUSⅡ软件开发平台,采用层次化、模块化与参数化的设计方法,设计并验证了一种性能良好的16QAM信号发生器。介绍了VHDL语言与16QAM原理,阐述了16QAM信号调制与解调的理论方法,设计并实现了正余弦载波产生、16QAM调制、解调等功能模块,给出整体调制解调的模块图与仿真波形。性能分析结果表明该系统设计可行。Based on VHDL and MAX＋PLUS II software development platform, a 16QAM signal generator with good performance is designed and verified by using hierarchical, modular and parametric design methods. The VHDL and 16QAM principle are discussed firstly, and then the theory of 16QAM signal modulation and demodulation is analyzed, and multiple functional modules, such as the sine and cosine carrier waves generation, 16QAM modulation and demodulation, are designed and implemented. Finally, the whole modulation and demodulation module chart and the simulation profiles are achieved, and the performance analysis shows that the design of the system is feasible.
