IEEE 802.15.3d-Compliant Waveforms for Terahertz Wireless Communications

Abstract

The terahertz electromagnetic band has been foreseen as a promising candidate to accommodate the everincreasing wireless data traffic. To this end, the development of novel transceiver architectures and signal processing solutions is crucial to handling massive data volume transmitted over terahertz wireless communications networks. In this paper, we propose a waveform that shows full compliance with the spectral emission mask imposed by the IEEE Standard for terahertz communications. The designed waveform exploits 99.3% of the total in-band energy admissible by this mask and provides an extra degree of freedom for out-of-band interference management. A proof-of-concept experiment is conducted using a 300 GHz photonics-based terahertz communications link to demonstrate the generation and wireless transmission of the proposed waveform. Experimentally validated bit error rates show that the proposed waveform outperforms the widely adopted raisedcosine waveform and the better-than-Nyquist waveform even when the Nyquist criterion for inter-symbol interference-free signaling is not satisfied. Moreover, an error-free transmission at 1.44 Gbit/s is achieved without employing complicated digital signal processing at the receiver side.

Photonic integrated circuits for 5G-and-beyond networks: enabling the mmWave band and beyond with InP-based photomixers in integrated transceivers

“…The design of the higher carrier frequencies communication systems is mainly a twofold issue, on one side the choice of efficient modulation schemes, and on the other side the low complexity of the development of an efficient sub-THz system. [16], [17]. Higher carrier frequency systems above the E-band (e.g.…”

Single- versus Multi-Carrier Terahertz-Band Communications: A Comparative Study

“…We first verify our assumption of Gaussian PHN for THz communications. We incorporate the PHN measurement results in [67] for a 300 GHz signal source, a PHN floor level of 𝐾 0 = −110 dBc/Hz, and 𝐾 2 = 10 ( 𝑓 cor = 1 MHz); we set 𝐵 = 10 GHz, which satisfies (17). We consider Tx PHN without loss of generality.…”

“…However, temporal broadening [14] and the challenging synchronization procedure question the feasibility of pulse-based modulation. IEEE 802.15.3d-compliant WFs are proposed in [17], where novel pulse-shaping designs reduce out-of-band (OOB) emissions. Several other projects revisit the physical layer for future B5G sub-THz systems.…”

“…In recent years, with the increasing maturity of terahertz technology, terahertz waves have been widely used in many application systems, such as terahertz detection [ 1 , 2 ], sensing [ 3 , 4 ], communication [ 5 , 6 ], and radar [ 7 , 8 ]. Especially in the application of 5G communication [ 9 , 10 ] and the technological development of 6G communication [ 11 , 12 ] in the future, terahertz communication technology has been widely considered by countries all over the world.…”
