This paper presents importance of beamforming technique for next generation broadband wireless mobile systems. Beamforming is a powerful means of increasing capacity, data rates and coverage of the cellular system. In this paper two beamforming techniques, Minimum Variance Distortionless Response (MVDR) and Linear Constraint Minimum Variance (LCMV) are presented. These techniques form radiation beams based on the received weight vector of the desired signal. Simulation has been carried out for two algorithms in MATLAB environment. The uniform linear array (ULA) and Uniform Rectangular Array (URA) smart antenna are used to receive the signal. The ULA contains 10 isotropic antennas. The element spacing is half of the incoming wave`s wavelength and the operation frequency is 9MHz. The URA consists of 10 rows and 5 columns of isotropic antenna elements. The spacing between the rows and the columns are 0.4 and 0.5 wavelengths, respectively.
