    • A communication system is presented. The system includes one or more transmitters configured to transmit a signal, where each of the signals generated by the one or more transmitters corresponds to a respective frequency. Further, the system includes a plurality of receiver front-ends configured to receive the signal transmitted by each of the one or more transmitters. The system also includes a plurality of remodulator modules configured to translate each of the received signals to a signal having a respective intermediate frequency. In addition, the system includes a combining module configured to combine each of the signals having respective intermediate frequencies to generate a single composite signal. Also, the system includes a single analog-to-digital converter configured to process the composite signal and generate a digital output. Additionally, the system includes a digital signal processor module configured to extract the signal transmitted by each of the one or more transmitters.
    • 介绍了通信系统。 该系统包括被配置为发送信号的一个或多个发射机,其中由一个或多个发射机产生的每个信号对应于相应的频率。 此外,该系统包括被配置为接收由一个或多个发射机中的每一个发射的信号的多个接收机前端。 该系统还包括多个重调制器模块,其被配置为将每个接收到的信号转换为具有相应中间频率的信号。 此外,该系统包括组合模块,其被配置为组合具有各自中间频率的每个信号以产生单个复合信号。 而且,该系统包括被配置为处理复合信号并产生数字输出的单个模拟 - 数字转换器。 另外,该系统包括数字信号处理器模块,该数字信号处理器模块被配置为提取由一个或多个发射器中的每一个传输的信号。
