'Intelligent' antenna system based on a spatial filter bank, automatically traces the use conditions of subscriber stations in which a simple system works with high efficiency

摘要

The distribution system (20) for the intelligent antenna system includes a spatial bank of filters which receive each signal, an antenna control circuit which controls each of the spatial filters, an antenna array which consists of multiple antenna elements, each of which receives the spatially filtered signal and sends it to the sub-station (50)
