Robust wideband beamforming

Year: 2010

Type: conference-paper

Abstract: Robust wideband beamforming with a real-time array testbed will be studied in this paper. For the practical consideration of uncertainty, channel impulse responses or channel transform functions of RF chains can not be obtained exactly due to the limitation of sounding and calibration procedure. Thus robust optimization will be applied to wideband beamforming. It is assumed that the uncertainty will be bounded and the worst case performance can be guaranteed by robust optimization. Finally, the optimal coefficients for a 2-dimensional filter bank to perform wideband beamforming will obtained.
