Fractional Fourier transform based beamforming in micro-cellular environment of wireless communication systems

Abstract

The next generation mobile services like variable bandwidth; desktop/multimedia with mobility and service personalization shall be enabled by putting new technologies and systems in use. In order to provide these services in wireless fashion the requirements on data rate, link quality, spectral efficiency, and mobility cannot be met with conventional beamforming. Therefore new beamforming techniques are essential to increase the spectral efficiency of wireless communication systems. In this paper a fractional Fourier transform (FrFT) based optimal beamforming in micro-cellular environments over AWGN channel is considered for reducing MSE at no extra computational cost. The results are achieved by use of FrFT based beamforming for a moving and accelerating source in a micro-cellular environment.
