实现多址通信的技术基础是信号的分割。利用信号在频率或时间上的正交性来对信号进行划分，从而进行多址传输。根据多址连接的调制方式，可将多址方式分为频分多址、时分多址、码分多址及空分多址等方式。目前在通信系统中应用广泛的多址技术可分为３类：频分多址（ＦＤＭＡ）?
The technical basis for implementing multiple access communication is signal segmentation. The signal is divided using the orthogonality of the signal in frequency or time to thereby perform multiple access. According to multiple access modulation, multiple access methods can be divided into frequency division multiple access, time division multiple access, code division multiple access and space division multiple access and other means. At present in the communication system widely used multiple access technology can be divided into three categories: Frequency Division Multiple Access (FDMA)?
