Multichannel lattice filter for an adaptive array processor with linear constraints

It is proposed to implement the linearly constrained adaptive array processor using multichannel lattice filter. Due to the Gram Schmidt orthogonalization properties of the lattice structure, the proposed realization converges faster and yields smaller estimation errors than the TDL counterpart. Computer simulation results comparing the performances of the mulichannel TDL and lattice filters for the linearly constrained adaptive array processing problem are presented.
