摘要
本文建立了宽带CDMA的阻塞模型,在此基础上,提出一种数字中频接收机的实现方案,并对主要电路的性能要求作了分析,给出了关键器件设计与实现的方法。
The article sets up the blocking model of wide-band CDMA. Based on that, the article then gives a type of CDMA IF digitization receiver and analyzes main circuit's requirement. The design and implementation of the circuit's key components are also discussed.
