Description/Abstract

Mismatches in the response of the components used in the analogue front-ends of adaptive beamformers can reduce their ability to produce deep nulls against broadband interferers. These mismatches can be removed through a process of calibration performed at start-up and, if required, on a regular basis to track changes in the component psila s response due to environmental changes. In this paper a hardware efficient scheme for compensating for channel mismatches is proposed based on pre-equalization of each channel using frequency domain equalization. The effectiveness of the proposed scheme is simulated and the improvement in broadband nulling is demonstrated on a hardware implementation of an adaptive beamformer.
