Increasing capacity of blind mobile system using pre-filtering technique

Abstract

Increasing mobile system capacity is a hot topic in communication research. A new beamforming technique using a pre-filtering process that decreases noise and interference effects to improve capacity of cellular systems is proposed. Simulation results show significant improvement over the conventional beamforming techniques. The simulation is based on the constant modulus algorithm as a typical blind beamforming technique. This capacity enhancement is achieved with slight increase in computational cost.
