PROJECT TITLE :

Base station beamforming technique using multiple signal-to-interference plus noise ratio balancing criteria

ABSTRACT:

The authors propose a coordinated multi-cell beamforming technique for signal-to-interference and noise ratio (SINR) balancing beneath multiple base station power constraints. Instead of balancing SINR of all users in all cells to the same level, the authors' propose a replacement approach to balance SINR of users in varied cells to totally different maximum potential values. This has the flexibility to permit users in cells with comparatively additional transmit power or higher channel condition to achieve a higher balanced SINR than that achieved by users within the worst-case cells. This multi-level SINR balancing drawback is solved using SINR constraints based mostly SINR balancing criterion and subgradient methodology. The simulation results support the optimality of the results through comparison with semi-definite programming-based mostly optimisation.
