摘要
介绍一种利用新器件特性实现全数字上变频的方法,包括射频频率范围内从基带信号的插值滤波器的设计、载波信号的产生,到针对射频信号高采样率的并行处理方法以及与数模转换器件的接口设计。与传统模拟方案相比,本设计具有更佳的性能、更低的成本和更好的灵活性,可广泛用于电缆调制解调器系统。
A new method to realize digital RF up-conversion is presented by using of the chips＇ new features, including the design of interpolation filter for base-band signals, the generation of carrier waves, the parallel processing method of RF signals and the interface design of DAC. Compared with traditional method, this design with the benefit of higher performance, lower cost and better flexibility can extensively be used in CMTS.
