SINR Evaluation for Improved Practical Coordinated Multi-point Clustering

Article

Abstract

Coordinated multipoint (CoMP) networks cooperatively process user equipment (UE) to eliminate inter-cell interference. CoMP networks convert the interfering signals into useful information by controlling the interference among adjacent cells. This is important for UE at the cell edge. This paper examines deployment of CoMP networks and investigates how CoMP communications can enhance the signal-to-interference and noise ratio (SINR) in practical inter-site and intra-site networks. In addition, we propose weighted clustering according to the average number of active users in the sector. Priority in forming clusters is given to sectors with more users. This reduces the error caused by the uniform UEs distribution assumption used by many researchers. We consider real city topography, terrain data, and UEs distribution to evaluate the received power and estimate the SINR improvement in real CoMP networks.
