Direct Data Domain Approach to Adaptive Antennas
Han Hong · Acta Simulata Systematica Sinica · 2004
A novel approach for efficient computation of adaptive weights in array antennas is introduced. It deals with the application of the direct data domain least-squares algorithm to adaptive antennas. This approach, unlike the conventional statistical techniques requiring for a covariance matrix of sample, is based on direct spatial processing of the array data. Simulation illustrates the effectiveness in estimating the amplitude of signal and the improvement in signal-to-noise ratio, and it can also be implemented to operate in real-time.
