Coded pilot synchronization in wide band sub-THz communication systems

Purpose and goal

Future 6G networks demand ultra-high data rates for advanced connectivity and wireless backhaul, driving interest in sub-terahertz (sub-THz) bands with wide bandwidths. This project develops and evaluates a coded pilot-assisted synchronization method for sub-THz links, enabling carrier recovery via a hybrid analog–digital design using low-speed ADC/DACs. The approach is cost- and power-efficient, modulation- and bandwidth-independent, supporting flexible deployment.

Expected effects and result

The coded pilot-assisted synchronization method will be develop and evaluate in an FPGA flatform and this synchronization method will be applied in a sub-THz link with sub-THz frontend modules. Transmitter and receiver modules will use separate LO sources, by applying this synchronization method, a real-time, high-data-rate link delivering several tens of gigabits per second is expected to be demonstrated.

Planned approach and implementation

--System simulation: Adaptation of the coded pilot-assisted synchronization method for sub-THz operation and performance analysis through simulation. --Hardware implementation: Integration of sub-THz front-end modules with a hybrid analog–digital architecture for carrier recovery. --Experimental validation: Demonstration of high-data-rate wireless links using high-order modulations and evaluation of EVM, BER, and frequency offset performance.
