FDM Frequency Division Mul-tiplexing频分复用一种多路复用技术。在FDM中,把传输频带分割成若干部分,每个部分均可作为一个独立的传输信道使用。FDMA Frequency DivisionMultiple Access频分多址是一种模拟多址技术。采用不同的载频来区分不同的站址,早期的模拟移动通信基本?
FDM Frequency Division Mul-tiplexing Frequency division multiplexing A multiplexing technique. In FDM, the transmission frequency band is divided into several parts, each part can be used as a separate transmission channel. FDMA Frequency Division Multiple Access is a type of analog multiple access technology. Using different carrier frequency to distinguish between different sites, the basic analog mobile communications early?
