Directional Active Noise Control with a Local Minimax Error Criterion
Applied Sciences, 2019 The traditional mean squared error (MSE) criterion can be formulated as a quadratic function of a vector of control filter coefficients, and it is easy to obtain optimal control filter coefficients. Although the MSE criterion can lead to noise reductions
