Fast convolution filtering is a powerful technique every DSP engineer should know. All but the shortest Finite Impulse Response (FIR) filters can be implemented more efficiently in the frequency domain than dir
filtering theoryIt has been demonstrated that the bilateral filter can be computed using a series of fast convolutions by approximating its Gaussian range kernel using trigonometric functions. A novel approximation that can be applied to any range kernel is proposed. Specifically speaking, an ...

Building management systems (BMSs) are increasingly integrating advanced machine learning (ML) and artificial intelligence (AI) capabilities to enhance operational efficiency and responsiveness. The transformation of BMSs involves a wide range of environmental, behavioural, economical and technical factors as...

a fast-convolution-based filtered orthogonal frequency division multiplexing (FC-F-OFDM) providing optimized multiplexing of filtered groups of cyclic prefix (CP)-OFDM physical resource blocks (PRBs) in a spectrally well localized manner. The presented subband filtering solution is able to suppress inte...
