Chapter 7, Problem P1P
Program Plan Intro
CDMA:
- It is known as “Code-Division Multiple Access”.
- Many radio communication technologies use the CDMA.
- It is an example of multiple accesses, where many transmitters can send data concurrently in a single communication channel.
- It belongs to the family of channel partitioning protocols and it also prevent in WLAN and cellular technologies.

One way to electrically or optically represent a binary 1 or 0 is to use current state modulation, which represents a binary 1 with the presence of voltage (on a copper cable) or the presence of light (on a fiber-optic cable). Similarly, the absence of light or voltage represents a binary 0.
