摘　　要：针对QAM调制技术在移动通信中的应用,文中提出了一种基于Altera公司CPLD器件和MICRO-DEVICES公司的RF2713(单片集成正交调制解调芯片)器件,用VerilogHDL硬件描述语言实现16QAM(正交幅度调制)调制器前端设计的思想和方法。该方法具有一定的扩展性,并且可用EPM7128SLC84-15实现,并在电路板上验证了此方法功能的正确性。通过修改VerilogHDL程序可以扩展成64,256制式的QAM调制方式。Aiming at the application of QAM modulation technique in the mobile communication, this article introduced a kind of thought and method which uses Verilog HDL hardware description language to realize the preceding design of 16QAM(quadrature amplitude modulation) ,based on the Altera company of CPLD device and MICRO-DEVICES company of RF2713(monolithic integrated quadrature modulator/demodulator) device. This method has some expansibility and it is realized by EPM7128SLC84-15, its feasibility has been validated in the circuit board. The QAM modulation mode may be extended to 64, 258 modulation mode by mending Verilog HDL program.
