Downlink Performance Improvement Using Base Station Cooperation for Multicell Cellular Networks

In this paper, we consider the multicell network which consists of several mobile stations (user terminal) and Base Stations (BSs) with multiple antennas at both BSs and user terminal respectively with random BS cooperation. We consider the cell interior users and use the rectangular and polar coordinate to calculate the distance of users from their home cell. Also, path loss model with distance-dependent is used for signal propagation. We use the BS cooperation scheme to the homogeneous multicell network and observe that BS cooperation also improves the downlink cell interior performance in the context spectral efficiency. BS cooperation is a scheme which improves the downlink Signal to Interference plus noise ratio (SINR) by canceling the Inter Cell Interference (ICI) for multi-cell cellular network. Further, it is noted that Coordinated Multipoint (CoMP) improves the system work. Showing the result of simulation, the cell interior SINR and channel capacity at various positions in the cell and also shows that the BS cooperation improves the capacity when compared to the no cooperation case.
