DOI: 10.1109/tcsii.2022.3160400
Abstract: The number of coefficients of multi-dimensional (M-D) finite-extent impulse response (FIR) filters increases exponentially with the number of dimensions leading to significantly high computational complexities. In this brief, we propose a minimax design method for… read more here.
