Abstract

satellite-mobile communication is currently one of the most growing areas in the field of telecommunications. However, the interference and the multi-path fading are still considered as major problems for receiving a dependable signal in such systems and this can generally lead to a significant degradation in their performance. One interesting solution to mitigate this problem is to utilize adaptive antenna array systems on the mobile user terminals. These systems will be used to steer the radiation pattern towards the satellite signal and to dynamically put nulls in the direction of the interference and the multi-path signals. This will be done in the real time by using smart signal processing algorithms; which are the key elements of the adaptive array antenna systems. These algorithms will be used to determine spatial signal parameters such as direction-of-arrivals (DOAs) of incoming signals and also to form the beams and steer them in the desired directions. In this paper, the adaptive antenna array systems for satellite-mobile communications has been discussed in terms of its advantages to the operator. The working principle of these systems, its applications for satellite-mobile communications, and also the drawbacks that may hinder its large-scale use have been discussed in details.
