Abstract
Phase noise (PN) poses a significant challenge in sub-terahertz (sub-THz) communications, alongside the necessity for low peak-to-average power ratio (PAPR) transmissions. This letter introduces an end-to-end learned single-carrier (SC) neural transceiver, which consists of a PN-resilient and PAPR-constrained transmitter utilizing a trainable pilot scheme combined with a deep neural receiver tailored for sub-THz. The learned transceiver effectively compensates for both correlated and uncorrelated PN and the flat-fading line-of-sight (LOS) channel while maintaining lower PAPR. The results show a substantial reduction in pilot overhead while delivering superior spectral efficiency and up to 1.2 dB PAPR gains over the conventional baselines.
期刊介绍：
IEEE Wireless Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of wireless communications. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of wireless communication systems.
