Explain the concept of CDMA.- CDMA is communication technique which is based on multiple-access scheme.
- The signal spreads to a wide bandwidth with using unique code which reduces interference and enhances system processing.
- Time division or frequency for multiple accesses is not required by CDMA.
- This results in improving the capacity of the communication system.
- It is a form of multiplexing that allows numerous signals to occupy a single transmission channel and optimize the use of the bandwidth.
- It uses the analog-to-digital conversion combined with the the spread spectrum technology.
