| 摘 要： | 本文通过现代DSP技术,以MATLAB/DSP Builder为核心的工具软件开发QAM（正交振幅调制）调制解调器。利用直接数字频率合成器DDS原理设计正交余弦信号发生模块;利用QAM正交调制与解调原理,实现对基带信号的调制与已调信号的解调;通过FIR滤波器的设计,实现对解调模块中的低通滤波,最终在FPGA器件上实现QAM调制解调器。

| Abstract: | Through modern DSP technoloy,MATLAB/DSP Builder as the core software tool is used to develop QAM modem.The DDS principle is used to design orthogonal cosine signal module.The QAM orthogonal modulation and demodulation principle is used to implement the base-band signal modulation and demodulation of the transferred signal.Using FIR design method,the low pass filter in the demodulator module is realized.The QAM modem is ultimately implemented on the FPGA device. |
