摘要
介绍了一种数字中频接收机的设计,对接收机的各个组成部分进行了原理分析和推导,包括可变带宽滤波器、ADC、基于多相滤波器的数字正交变换、抽取滤波器设计、基带信号处理单元设计,得出样机的各样性能参数。
An approach for designing digital -intermediate frequency (IF) receiver is introduced, the principle analysis and deduction of all parts of the receiver are performed including design of available - band filter, Analog- to -Digital Converter(ADC), digital orthogonal transforms based on digital polyphase filter, decimation filter, baseband signal processing unit. Finally parameters of the receiver are obtained.
