What are the sources of interferences in mobile communication?
The common types of interference in cellular networks are: self-interference, multiple access interference, co-channel interference (CCI) and adjacent channel interference (ACI). Self-interference is induced by signals that are transmitted on a shared transmitter.
How can mobile communication reduce interference?
Reduce the power level: The reduction in radio frequency power of wireless signals is an effective method of interference mitigation. Filtering and equalizers: In communication channels whose characteristics are known, filters can be incorporated for interference mitigation.
What is inter-cell interference in LTE?
Inter-cell interference coordination (ICIC) is a promising technology for alleviating this degradation and improving the bit rate at cell edges. In the LTE standard, an interface between adjacent base stations is specified for exchanging ICIC information.
How does the interference management increase the capacity?
By increasing its transmission power, a small cell may extend its coverage area and serve additional UE devices. The resulting small-cell range extension allows macro cells to offload more traffic to small cells, thus increasing the overall network capacity.
