Abstract	Summary form only given. Recent years, beamforming techniques have received great interests and it can achieve performance and capacity enhancement without the need for additional power or spectrum. They can be implemented through conventional beamforming, minimum variance distortionless response (MVDR) beamforming, and linear constrained minimum variance (LCMV) beamforming. In conventional beamforming, the antenna mainlobe is steered toward the desired signal. In MVDR beamforming, an antenna pattern is formed to maximize the output SNR while maintaining a constant gain in the direction of the desired signal. The LCMV beamforming is developed from MVDR beamforming with additional linear constraints to improve its robustness. While multiple interferers are considered, the LCMV beamforming can be implemented by putting nulls in the directions of interferers. This poster investigates the outage probability of a wireless system with conventional beamforming using a uniform linear array (ULA) beamformer. A simplified beamforming model is used in deriving closed-form outage probability expressions and its accuracy is examined by simulation. Fading statistics of Rayleigh, Rician, and Nakagami are used to characterize the desired signal, whereas interferers are assumed to be subject to Rayleigh fading.
