A simple hybrid coordination scheme with semi-distributed mode in multi-cell network

The problem of distributed coordination in multi-cell wireless network has been concerned in the research community recently due to its ability to enhance intended signal and mitigate interference in the system. In the previous research, the design of beamforming weights at transmitter has been addressed from the perspective of egoism and altruism concepts considering the tradeoff between egoistic and altruistic solutions. The main contribution of this paper is to extend the existing strategy and exploit a much simpler hybrid coordination scheme with semi-distributed mode in multi-cell wireless network using the analytic hierarchy process. The significant advantage of our approach is to provide transmitter with a method which is easier to achieve compared with the existing pattern in a semi-distributed way. The performance of proposed scheme is finally illustrated through the numerical simulation results.
