Executive Summary

The interference reduction capability of antenna arrays and the power control algorithms have been considered separately as means to decrease the interference in wireless communication networks. In this paper, the authors propose Smart Step closed-loop Power Control (SSPC) algorithm in wireless networks in a 2D urban environment with Constrained Least Mean Squared (CLMS) algorithm. This algorithm is capable of efficiently adapting according to the environment and able to permanently maintain the chosen frequency response in the look direction while minimizing the output power of the array.
