Apply FASTICA to smart antenna technology in wireless communications systems

Smart antenna technology, as one of the key technologies of the wireless communication, increases the traffic capacity of a system, enlarges the coverage range of a cell, and improves the quality of the signal. It is therefore of practical interest to research smart antenna technology applied to wireless communication. In this study, we focus on FASTICA (fast independent component analysis) algorithms with smart antenna at the wireless communication. It can reduce interference and suppress multi-path effect in the up (reverse) link. At first, we introduce a general overview of smart antennas. Second, we narrate the FASTICA algorithms. At last, we utilize FASTICA to separate the demodulated mixed signals. The simulation study makes know FASTICA arithmetic is a new valuable way and is able to distinguish communication signal from many different noises effectively.
