CodeDivisionMultiplex
Code Division Multiplexing (CDM) is a technique used in digital communications to allow multiple signals to share a single communication channel simultaneously. It is a form of spread spectrum modulation where each signal is assigned a unique code, enabling them to coexist without interference. This method is widely employed in wireless communication systems, including satellite, mobile phones, and military applications, due to its robustness against noise and interference.
The core principle of CDM involves spreading the bandwidth of each signal over a wider frequency range
One of the most prominent applications of CDM is in **Code Division Multiple Access (CDMA)**, a digital
CDM also plays a key role in satellite communications, where it helps mitigate signal degradation caused by
