Abstract: The standards of wireless communication systems have been developed from single-user to multi-user communications so that users can gain a higher data transmission speed, a reduction of power consumption and wider coverage. For the multi-user transmission, a base station transmits data to a number of users employing the same frequency at the same time. So far, a beamforming technology has been taken into account to upgrade the multi-user communication systems. The beamforming technology helps the systems avoid interference in the direction of main beam. In general, the interference cannot be eliminated when it comes in the region of main beam. This means that the beam width directly affects the distance between adjacent users. Furthermore, the angular separation between adjacent users affects the beamforming performance. Therefore, this paper analyzes and simulates the effect of angular separation between adjacent users. In case that desired and interference signals are both located in the main beam region, the Signal to Interference plus Noise Ratio (SINR) must be very low. However, producing a narrow beam width lets users come close to one another. This can be achieved by employing a large number of antenna elements.
