Array receiver with subarray selection
Description / Description
Smart antennas are capable of continuously modifying their spatial emission and reception patterns to maximize communication efficiency. They allow to augment the systems range, reduce interference and even reach users with obstructed line-of-sight. However, the signal processing operations and algorithms associated with smart antennas is highly complex and costly, and that is the main drawback which as prevented their widespread deployment until now.
Our simplified approach to process the signals from array antennas allows us to attain the performance levels possible with large arrays at a price and complexity point comparable to that of standard one antenna access point.
Our approach also provides immunity to interference and intrusion (piracy) right at the physical layer.
The proposed method consists in selecting a reduced subset of antennas within the full antenna array to subsequently perform dynamic processing on the subset only. Since the dynamic processing is performed on the subset only, the complexity and computational overhead is reduced by at least an order of magnitude with only negligible loss of performance compared to full-array processing.
