频分多址(FDMA)是把通讯系统的总频段划分成若干个等间隔的频道(或称信道)分配给不一样的用户使用。这些频道互不交叠,其宽度应能传输一路数字话音信息,而在相邻频道之间无明显的串扰。频分多址的频道被划分成高低两个频段,

(Frequency Division Multiple Access (FDMA) divides the total frequency band of the communication system into several equally spaced frequency channels (or channels) and assigns them to different users. These channels do not overlap each other and should be wide enough to transmit one channel of digital voice information without significant crosstalk between adjacent channels. Frequency division multiple access channels are divided into high and low frequency bands.)
