作为TDM的改进版本,STDM动态分配时隙,仅在用户有数据传输时分配资源。例如ATM网络通过信元交换实现带宽按需分配,信道利用率比传统TDM提高30%-50%,但需要更复杂的控制机制。 四、波分复用(WDM) 波分复用是光纤通信中的频分复用技术,使用不同波长的激光在同一光纤传输。密集波分复用(DWDM)可...

Multiplexing can create channels in frequency, time, etc., and the corresponding terms are then frequency division multiplexing (FDM), time division multiplexing (TDM), etc. [1, 3]. Since the amount of spectrum available is limited, we need to find ways to allow multiple users to share the...
An FDM-TDM transmultiplexing system for a modulation demodulation device which is applicable to a regenerative repeating system of a satellite or a ground radio communication system is disclosed which uses chirp-z-transform. A chirp filter (102) is implemented with a digital circuit. The circuit ...
TDM finds its application mainly in a digital communication system, in cellular radio and in satellite communication system. Related Terms: Wavelength Division Multiplexing (WDM) Frequency Division Multiplexing (FDM) Modulation Communication System
a low level ofmutual interference, so long as they are on sufficiently separatedoptical frequenciesand theoptical power levelsare not too high. This is a form of FDM, but since optical wavelengths, rather than frequencies, are usually specified, it is known aswavelength division multiplexing(WDM)...
Wavelength-division multiplexing (WDM) is another technique that is similar to FDM but used in optical communication systems.In WDM, in order to allocate each input signal to a wavelength band, we split the possible bandwidth of an optical fiber into a number of wavelength bands: ...
