| 摘 要： | 通过对HFC广播有线电视信道中的16QAM信号的研究，分析了噪声及信道特性对QAM信号的影响，提出了用自适应均衡器来提高QAM信号的传输质量，并用复杂可编程逻辑器件(CPLD)实现该均衡器。采用CPLD技术可大大增加均衡器的可靠性、灵活性，同时也缩短了设计周期。该均衡器可运用于实际的有线通信系统，从而为复信号的均衡提供了一个技术方案。

| Abstract: | In this paper, a 16QAM in BC of HFC is studied, and the effects of noise and channel characteristic on QAM are analyzed. A scheme of improving the quality of QAM by adopting adaptive equalizer is put forward, which is fulfilled with CPLD devices. The technology can improve the credibility of the equalizer and reduce the period of design. At present, the datum about the technology of the equalization of complex signal is very less, while the complex of equalizer can be apply to the system of communication. So it is a feasible technology method. |
