Abstract

Abstract In the industrial world, a trend towards connected, robotic and intelligent factories is on the rise to face competition from countries with low production costs. The industrial revolution ‘Industry 4.0’ is considerably reducing the boundaries between the physical and digital worlds. This has given rise to interconnected factories in which people, machines and products interact with each other using smart sensors. This paper presents a comparison between a pulse-modulated Discrete Wavelet Packet Transform (DWPT) system and an Orthogonal Frequency Division Multiplexing (OFDM) multicarrier modulation system in a noisy industrial propagation environment. This to provide an alternative to conventional high-rate wireless communication systems using an Industrial Internet of Thing (IIoT).
