摘要
全数字 DS/CDMA信号接收机既可以采用中频采样方案 ,也可以采用基带采样方案 .在设计时 ,按频率采样定理合适选择芯片的工作主频、PN码速率、中频采样速率、基带采样速率和中频频率等参数是系统设计的一个重要方面 .
Both intermediate and base band frequency sampling schemes may be used in all digital DS/CDMA receiver. It is very important to choose suitably parameters such as motherland frequency , chip rate , intermediate frequency sampling rate, base band sampling rate and intermediate frequency for the system design of digital DS/CDMA receiver.
