摘要
正交振幅调制QAM(Quadrature Amplitude Modulation)以其高频谱利用率、高功率密度等优势成为宽带无线接入和无线视频通信的重要调制方式。本文介绍16QAM调制解调的原理,然后给出原理框图并根据框图设计电路,最后提出了一种基于Systemview的16QAM实现方案。
For its high spectrum efficiency, high power density advantage into broadband wireless access and wireless video communications, QAM （Quadrature Amplitude Modulation）is important modulation,This article first introduced the principle of 160AM modem, and then gave diagram and in accordance with the circuit diagram of the experimental design, the last a Systemview based on the realization of 160AM program was given,
