N2 - In this paper, based on the generalised sidelobe canceller (GSC), we propose a novel broadband adaptive beamformer, where its quiescent vector and blocking matrix are replaced by a series of two dimensional frequency invariant filters (FIFs). The new quiescent vector forms a beam pointing to the signal of interest, whereas the new blocking matrix forms a number of beams pointing to other directions, with a zero response to the signal of interest. As opposed to standard beam space techniques, the FIFs need not have a very low sidelobe level, and the number of FIFs that can be implemented also increases. Compared with the traditional GSC, a faster convergence speed is achieved in addition to a resultant frequency-invariant beam pattern, as shown by simulations.
