Performance Evaluation of Satellite Beamforming System with Square Array Antenna

In this paper, we present an efficient architecture of the adaptive beamforming satellite system based on the planar (square) array antenna. It is consisted of an Angle-of-Arrival (AOA) estimator for estimating AOAs of signals, an adaptive beamformer for suppressing interference signals and enhancing the desired signals, a signal processing & D/B unit for saving and processing data obtained from the received signal, and a transmission beamformer for transmitting signal information. Also, we provide computer simulation results to evaluate the performance of the presented system with different sizes of the square antenna array.
