摘要

为了交通远程信息处理(路线引导、车队管理等)的目的，需要车辆上的终端能够准同时接收蜂窝电话(GSM)和卫星导航(GPS)。传统的方法使用两个完整的接收器来完成这两个任务。我们描述了一种基于GSM信号的时分复用结构的组合式接收机的节省成本的解决方案。我们的解决方案基于用于中频数字化的带通- σ - δ ADC。

An IF digitizing receiver for a combined GPS/GSM terminal

For the purpose of traffic telematics (route guidance, fleet management etc.) one needs terminals on the vehicle for the quasi-simultaneous reception of cellular phone (GSM) and satellite navigation (GPS). A conventional approach uses two complete receivers for these two tasks. We describe a cost-saving solution for a combined receiver which relies on the TDM structure of the GSM signal. Our solution is based on an bandpass-sigma-delta ADC for IF digitizing.
