FAST CONVERGENCE SOCP-PR TECHNIQUE FOR POWER MINIMUM PROBLEM IN MULTI ANTENA TRANSMISSION

Abstract

Improving the efficiency of using the new generation radio transmission
network is of great concern in the scientific community around the world. In
particular, the problem of minimizing transmit power of the antenna diversity
system in the wireless transmission network has used many optimization
techniques to solve. Besides the goal of determining the optimal value, improving
convergence speed for the problem is also studied. The nonsmooth (NSM)
optimization technique has been introduced as an efficient candidate that solves
the problems at nearly optimum. However, the NSM method requires many
iterations to derive an efficient result due to the slow convergence rate. In this
work, we proppose SOCP-PR optimization technique for multi antena
transmission model that improves the convergence rate in power minimum
problem significantly.
