摘　　要：现代通信越来越依靠全数字处理技术 ,本文介绍了用Altera开发系统的硬件描述语言(AHDL)实现全数字正交幅度调制 1 6QAM调制器的思想和方法。如何将全数字算法用硬件描述语言实现具有一定的灵活性和创新性 ,本文给出了这方面设计的思路和具体的设计过程。事实上 ,我们已经用可编程芯片FLEX1 0K系列中的EPF1 0K1 0LC84 4实现了整个设计 ,并在PCB板上验证了功能的正确性 ,得到了较满意的波形。虽然我们的设计还有欠缺 ,如 :未考虑数字成形滤波器 ,调制器的速度也较低 ,但我们的设计具有可行性和先进性 ,对其他的全数字调制器如QP SK、64QAM等的实现具有重要的指导意义。All\|digital processing technology is indispensable for modern communication. This paper introduces the idea and method of implementing the all digital quadratic amplitude modulation 16QAM modulator by Altera Hardware Description Language of the Altera developing system. How to implement all digital algorithms by Hardware Description Language is of certain flexibility and innovation. This paper provides the idea and specific consideration for this design. As a matter of fact, we have achieved whole design by using the programmable chip EPF10K10LC84\|4 that belongs to FLEX10K series and have testified the validity of its function in Printed Circuit Board. We have obtained some satisfactory waves. Although our design still has defects (For example, we have not considered digital formed filter and the rate of modulator is lower.), our design is both feasible and advanced.It is of significance to the implementation of other digital modulators such as QPSK and 64QAM.
