Hello, readers welcome to the new post. Today we will discuss Difference between co-channel interference and adjacent channel interference. The operation of a cellular system is based on interference. Interference is the main issue for the enhancement of the capacity of the system. Normally two categories of interference are used in the cellular system first one is co-channel and the second one is adjacent channel interference.
In this post, we will cover different points to find the differences of Difference between co-channel interference and adjacent channel interference. So let’s get started.
What is co-channel interference?
- Co-channel interference is a type of radio signal interference. Usually, radio frequency interference exists when signals through outer sources with a combination of frequencies affect the signal reception.
- This interference exists through 2 signals at one channel. It has an effect on the radio modules such as wireless operating devices for example mobile phones and wifi devices.
- This interference is considered a type of electromagnetic and radio frequency interference.
- There are different types of this interference such as wifi interference and crosstalk.
- Crosstalk exists when much communication exists on similar mobile modules. It is called crosstalk.
- The main consequence of co-channel interference is the elimination of the operation of radio channels comprising internet channels.
- For instance, the main reason for the reduction of wifi use is co-channel interference with the other cause is adjacent channel interference.
- Co-channel interference also consequences in the elimination of wireless mobile communication like messages and calls.
Adjacent channel interference
- Adjacent channel interference is a type of interference that is produced by the extra power through a signal in an adjacent channel.
- It is normally generated through improper filtering, improper tuning, and frequency control.
- Adjacent channel interference exists through a different channel.
- Through the use of accurate filter and channel configuration, the adjacent channel interference can be reduced
- This channel interference exists in radio channels when not required energy from the closers channel falls on the required bandwidth.
Co-channel interference vs. adjacent channel interference
- CO channel interference exists between signals from co-channels, and adjacent channel interference exists between the signals from the channel that have the same frequency as the desired signal.
- Co-channel interference between the signals from the same source and adjacent interference between two different sources’ signals
- Co-channels exist on the same source and adjacent channels on different sources.
- Co-channels are separated at some distance to reduce this interference, and a proper filter is used for adjacent channel interference.
What is meant by adjacent channel interference?
- Adjacent channel interference is caused when transmissions are delivered on adjacent or partially overlapping channels. The channel moves over an overlapping channel that adds noise and interface. That is bad as compared to co-channel since it gets and operates like noise.
What is an example of co-channel interference?
- The common examples of co-channel interference are radio stations trying to broadcast audio on the 98.7FM channel.
What are the different types of interference in cellular communication?
- The basic types of interference in cellular networks are self-interference, co-channel interference (CCI), multiple access interference, and adjacent channel interference (ACI).
- Self-interference is added with signals that are transmitted through the shared transmitter.
What causes co-channel interference?
- Co-channel interference occurs when two access points in the network exist on the same channel. Resulting in interference that reduces signal strength and causes issues at the user end experience.
What is co-channel interference in RF?
- Co-channel interference is a certain type of electromagnetic interference and radio frequency interference. It occurs when two signals on the same channel cross with each other. The main result of co-channel interference is a reduction in the operation of radio wave channels.
How can we reduce co-channel interference?
- Reducing base station transmitter-receiver power can also minimize co-channel interference. If co-channel interference in mobile communication is reduced, it can cause a crosstalk effect. The use of directional antennas at the base station reduces co-channel interference
What are the two methods of interference?
- Interference has two types: constructive and destructive. Constructive interference results when wave crests or troughs overlap and increase amplitude, and destructive interference exists when crest and trough overlap, minimizing amplitude.
What is a possible solution to cochannel interference?
- The basic replacement of cochannel interference (CCI) mitigation for FDMA/TDMA systems like GSM is commonly used in industry and comes with cell sectorization, dynamic channel assignment, and frequency hopping.
