Implementation of Adaptive algorithms to improve QoS in Base station Antennas

Abstract

Mobile communication has seen remarkable development worldwide in recent years. Developments in the VLSI design and heat sink design have decreased both the power consumption and the size of the mobile station. The base station is no exception, but customization of the antennas is the bottleneck. The base station transmits electricity to the user in all directions. The power is certainly squandered. In addition, the user gets a tiny percentage of the overall radiated power. As the emission and reception pattern of the base station are the identical, this implies that the interfering signal comes from all directions to the base station. The idea of sectorization is proposed to enhance the SIR. In the sectorisation, directional antennas are employed, which increases SIR only in the range of azimuthal planes. The zone changes as a user travels from one sector to another. Thus the radiation pattern in the region is predetermined using switched beam technology and the user is supplied azimuthally across all geographical areas. This does not provide for the efficient handling of the conflicting signals. Smart antenna technology offers adaptive beam creation by executing adaptive algorithms on the Digital Signal Processor in order to improve QoS. Therefore, the base station concentrates and monitors the user and beam creation also adapts to the spatial position of the other user.
