Interference performance analysis in COMP for downlink system

In the cellular communication system, the co-channel interference (CCI) deteriorates the users´ performance seriously. Since in the Coordinated Multiple Point (COMP) technology every cell can utilize the all physical resource blocks (RB) instead of part of them, therefore CCI is more seriously than other schemes. This paper talks about the sources and features of downlink CCI in COMP, and proposes a network scheme that can deal with the question. Through simulation, the paper obtains a suitable coordinated region and proves the scheme is feasible and meaningful.
