摘要
ＱＰＳＫ是ＨＦＣ上行通道一种有效的调制方法，将ＨＦＣ上行通道的输入噪声抽象为一个窄带干扰模型，对其采取非线性抑制措施，构造了一个非线性窄带干扰抑制器，把非线性的ＤＬＭＳ２和ＤＲＬＳ２应用到ＱＰＳＫ调制系统，对其各项性能进行了仿真研究。
【Abstract】 QPSK is an efficacious modulation method on the upstream channel in the HFC. Abstract the ingress noise to a model of narrow-band interference and take a nonlinear suppression measure. Construct a nonlinear narrow-band interference suppresser and simulate in the nonlinear DLMS2 and DRLS2 algorithm are used QPSK modem system and performances are analyzed.
