宽带HFC网络中的调制方式与窄带干扰抑制的分析
Analysis of modulation system and narrow band interference suppression in wide band HFC network
【摘要】 在整个5~42MHz回传通路频带内,对采用16QAM调制方式的HFC系统,构造了一个非线性窄带干扰抑制器,并应用非线性算法对带宽小于100kHz的窄带噪声进行非线性抑制。
【Abstract】 In this dissertation constructs a nonlinear narrowband interference is constructed and nonlinear algorithm is applied in the16QAM system to suppress the narrowband Interference with a band-width of less than100KHz in the upstream channel from5MHz to42MHz .[
