Abstract: The first step to design an efficient terahertz (THz) system is to find out suitable waveforms and modulation schemes that can be used in THz wireless system. Towards this end, a compromise between low-complexity and high data-rate had to be considered when selecting the appropriate transmission technique. The purpose of this work is to study the feasibility of THz system at a short distance by means of pulse-based modulation. To do that, a multi-band on-off keying (MB-OOK) transceiver has been presented and analysed under a channel model that considers both line-of-sight (LOS) and non-los (NLOS) components. We examined three approaches named monoband OOK, 4 sub-bands OOK and 8 sub-bands OOK. Simulation results carried out for the three approaches. A data rate of 125.09 Gbps can be supported at 20 m using the 8 sub-bands approach with a bit error rate (BER) less than 10⁻³.
