    • A transmitter of a communication system includes a spectrum dividing section which divides a transmission signal into a plurality of sub-spectra at a first sampling speed F1 and combines one or more low-speed intermediate composite signals from the divided sub-spectra, and a multiplexing section which multiplexes the intermediate composite signals at a second sampling speed F2 faster than the first sampling speed F1 (F2>F1) and distributes to a broadband. A receiver includes a demultiplexing section which extracts one or more low-speed intermediate composite signals from a reception signal at the second sampling speed F2, and a spectrum combining section which combines the intermediate composite signals at the first sampling speed F1 and extracts the sub-spectra to re-combines the transmission signal.
    • 通信系统的发射机包括频谱分割部分,其以第一采样速度F1将传输信号分成多个子频谱,并且组合来自分割子频谱的一个或多个低速中间复合信号,以及复用 该部分以比第一采样速度F1(F2> F1)更快的第二采样速度F2复用中间复合信号并分配到宽带。 接收机包括从第二采样速度F2的接收信号中提取一个或多个低速中间复合信号的解复用部分,以及以第一采样速度F1组合中间复合信号的频谱组合部分, 光谱重新组合传输信号。
