Near-end machine far-end machine fiber optic machine digital communication cell phone signal amplifier base station signal repeater
Today's world is a highly noisy environment and mobile or cellular communication is increasing at a rapid pace.
Anything that interferes, disrupts, or damages mobile communication signals is labeled interference.
In cellular communication systems, interference can be classified as co-channel interference or non-cochannel interference. Near-end far-end interference is one type of non-cochannel interference that occurs in mobile communication systems. We will explore interference in communication systems as well as take a closer look at this particular type of interference in this article.
Near-End Far-End Interference in Mobile Communication Systems
* System-generated cellular interference can be classified into co-channel interference and non-co-channel interference.
* The signals adjacent to the frequency of the desired signals interfere with mobile communication and are called adjacent
channel interference.
* The type of interference that only exists in mobile or cellular communication systems is called near-end far-end interference.
Near-end far-end interference only exists in mobile or cellular communication systems.
The occurrence of near-end far-end
interference is in relation to the distance between the mobile unit and the base station, which is compared with the distance to
another mobile transmitter.

When Does Near-End Far-End Interference Occur?
Consider a mobile unit at a relatively far distance of d1 from the desired base station transmitter. The mobile unit is at a
distance of d2 from the undesired adjacent mobile transmitter. Let the distances be such that d1> d2. When the two transmitters happen to transmit signals simultaneously, then the signals received by the mobile unit from the desired source are masked by the signals received from the undesired source.
Another scenario that leads to near-end far-end interference is when a base station receives signals simultaneously from the mobile units that are located at unequal distances from the base station. In this particular case, the power difference due to path loss between the base station and the two mobile units is defined by a term called near-end-to-far-end ratio interference.
The near-end-to-far-end ratio-interference is expressed as the ratio of path loss at distance d1 to path loss at distance d2.
The near-end far-end interference is a unique phenomenon that only occurs in mobile communication systems. It can occur within one cell or within cells of two mobile radio systems. Cadence offers software tools for designing near-end far-end interference mitigation techniques for mobile communication systems.
The severity of interference in mobile communication is high in urban areas.
A high radio frequency noise floor is one of the
major reasons that urban areas are prone to interference.
There are more mobile stations and base stations in big cities compared
to rural and suburban areas, and this increases the influence of interference on mobile communication in urban areas.
