Separable Least-Mean Squares Beamforming

Large-scale antenna systems have attracted much research efforts due to its application to modern mobile commu- nications systems. Designing such arrays, however, can be chal- lenging due to the computational efforts of classical signal pro- cessing methods. To tackle this issue, we investigate Kronecker- separable adaptive filtering methods. Simulation results suggest that this approach exhibits better convergence properties in some scenarios compared to the classical adaptive filtering benchmark.
