Iterative optimization of SINR equation based on polarization ratio parameters

For the SINR (signal-to-interference-and-noise-ratio) equation based on the polarization ratio parameters, an optimal polarization method called iterative optimal polarization (IOP) was presented. The IOP scheme employs the big and small circle local optimal solutions as basic frames. These two frames are iterative each other, and every one utilizes the results from the other, and transfers the own results to the other. The simulation results show that IOP method is an effective method for optimal polarization. After several iterations, the final optimum and optimal polarization point can be obtained, and the average relative errors of the optimum obtained with IOP related to the actual optimum are very small.
