Abstract

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 Microdevices Company of RF2713(monolithic integrated quadrature modulator/demodulator) device.This method has some expansibility and it is realized by EPM7128SLC8415.The QAM demodulation mode may be adapted to 256 demodulation mode by mending VerilogHDL program.
