FHCDMA Meaning and
Definition
-
FHCDMA stands for Frequency Hopping Code Division Multiple Access. It is a digital cellular communication technique used in mobile communication systems. This technique combines the principles of frequency hopping spread spectrum and code division multiple access to provide multiple simultaneous connections between mobile devices and a base station.
In FHCDMA, frequency hopping is used to divide the available frequency band into multiple smaller frequency channels. These channels are then dynamically assigned to different users on a time-division basis. Each user is assigned a unique code that allows them to differentiate their signals from others within the same frequency channel.
The frequency hopping capability in FHCDMA helps to minimize interference and improve resistance against signal fading caused by multipath propagation and external interference. It achieves this by rapidly changing the carrier frequency during transmission, thus spreading the transmitted signals across a wide frequency band.
FHCDMA offers several advantages over other multiple access schemes. It provides better capacity utilization, as multiple users can share the same frequency band simultaneously. It also offers enhanced security, as the frequency hopping and unique codes make it difficult for unauthorized users to intercept or interfere with the signals.
Overall, FHCDMA is a digital cellular communication technique that combines frequency hopping spread spectrum and code division multiple access to provide efficient and secure communication between mobile devices and base stations.
