THz Wireless Systems Design for Personal Area Networks Applications

Terahertz (THz) communication is a potential technology for wireless personal area networks. In this paper, we develop a chip set for on-off-keying (OOK) modulation based THz transceivers which include carrier generators, modulators, THz amplifiers, and baseband amplifiers. Specifically, the chip set integrates the circuit blocks for the OOK modulation. In addition, it also includes the THz amplifier modules to extend the coverage of transmission. For this chip set, we experimentally demonstrate the feasibility of the wireless communication at THz frequency bands and assess performance using the bit error rate (BER) analysis. We estimate the BER results by calculating the signal-to-noise ratio (SNR) based on the eye diagram and confirm the accuracy by comparing with actual BER tester measurements and Monte Carlo simulations.
