    • A system for receiving information, the system comprising a receiver being configurable to receive signals within a plurality of first frequency bands and output a second signal relating to a signal received within a selected one of the first frequency bands, a processing element adapted to receive and process a third signal being within a predetermined, second frequency band, each first frequency band being wider in frequency than the second frequency band, and an intermediate element adapted to receive the second signal, generate the third signal by selecting, from the second signal, information with a frequency within the second frequency band, and output the third signal. Thus, in satellite communication, a 2 LO LNB may be made to appear as a 4 LO LNB seen from the Modem.
    • 一种用于接收信息的系统,所述系统包括:接收器,其可配置为接收多个第一频带内的信号,并输出与在所述第一频带中选定的一个频带内接收的信号有关的第二信号;处理元件,适于接收 处理第三信号,所述第三信号在预定的第二频带内,每个第一频带的频率比所述第二频带的宽度更宽;以及中间元件,适于接收所述第二信号,通过从所述第二信号中选择第二信号来生成所述第三信号, 具有第二频带内的频率的信息,并输出第三信号。 因此,在卫星通信中,可以使2 LO LNB看起来像从调制解调器看到的4 LO LNB。
