Optimized Single Carrier Transceiver for Future Sub-TeraHertz Applications

Résumé

The performance of sub-THz communications, contemplated for the next generation of wireless networks, are significantly degraded by oscillator phase noise. In this paper, we address the design of a single carrier transceiver resilient to phase noise. This problem is treated in two steps: First, we derive for phase noise channels the optimum symbol detection criterion. Second, we propose a phase noise robust modulation scheme with a comprehensive and efficient structure. System level simulations modeling the sub-THz propagation channel of a rich outdoor environment through ray tracing are also presented. Results show that optimizing the modulation and demodulation schemes is necessary to achieve high spectral efficiency in the presence of phase noise.
