The Research of Beam Forming Algorithms In Cognitive Radio Systems

Abstract

In view of the problem of CO frequency interference in the heterogeneous networks of cognitive radio, this paper presents a method of CO processing by macro cellular and micro cellular cells. A beam forming algorithm for maximizing the network of the user is presented, which is based on the orthogonality of multiple antennas and different geographical locations.The simulation results show that the proposed algorithm can effectively improve the transmission speed between the sub users, so as to improve the utilization of frequency.
