    • A GNSS receiver having an IF process engine is disclosed. The IF process engine provides a plurality of carriers with different frequencies and down converts IF signals into baseband signals by using the carriers in a time division multiplex (TDM) schedule. The IF process engine has a local oscillator part for generating the carriers with different frequencies; an IF down-converter for respectively mixing the IF signal with the carriers generated by the local oscillator part to generate IF removed signal segments; a time division multiplex (TDM) controller for scheduling the respective mixing operations of the IF down-converter for the IF signal with the respective carriers; and a buffer for storing the IF removed signal segments generated by the IF down-converter.
    • 公开了具有IF处理引擎的GNSS接收机。 IF处理引擎提供具有不同频率的多个载波,并且通过使用时分复用(TDM)调度中的载波,将IF信号下变频为基带信号。 IF处理引擎具有用于生成具有不同频率的载波的本地振荡器部分; 用于分别将IF信号与由本地振荡器部分产生的载波混合以产生IF去除的信号段的IF下变频器; 时分复用(TDM)控制器,用于调度具有各个载波的IF信号的IF下变频器的各自的混合操作; 以及用于存储由IF下变频器产生的IF去除的信号段的缓冲器。
