摘要
针对QAM调制解调技术在移动通信中的应用,提出了一种基于A ltera公司的CPLD器件和M icro dev ices公司的RF 2713(单片集成正交调制解调芯片)器件,用V erilogHDL硬件描述语言实现64QAM(正交幅度调制)解调器后端编码设计的思想和方法。该方法具有一定的扩展性,并且用EPM 7128SLC 84 15实现了该设计。通过修改V erilogHDL程序可以适应256制式的QAM解调。
Aiming at the application of QAM modulation and demodulation technique in the mobile communication, this article introduces a kind of thought and method which uses VerilogHDL hardware description language＇to realize the design of backend design of 64QAM （Quadrature Amplitude Modulation） demodulator, 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. The QAM demodulation mode may be adapted to 256 demodulation mode by mending VerilogHDL program.
