Optimization of Power Consumption in MIMO Cellular Networks using Dynamic Semi Definite Relaxation

In this paper, the optimization of power consumption in MIMO cellular networks to improve the performance using dynamic semi-definite relaxation in terms of signal-to-interference-and-noise (SINR) ratio and optimal transmission power (OTP) is done. A MIMO cellular network where a base station (BS) can transmit data symbols to a fixed mobile station (MS) is considered. The algorithm is designed to decrease the number of active cooperation links and simultaneously optimize the beam forming vectors between the cooperative BSs subject to signal-to-interference-and-noise-ratio (SINR) constraints at the mobile station. We first propose dynamic algorithm based on MATLAB to solve the power optimization problem. Then comparison of the peak OTP, peak SINR, average OTP and average SINR of the proposed scheme with existing one is done.
