Fronthaul networks serve as crucial infrastructure, bridging wireless access with fiber networks and handling vast data volumes. Looking ahead, 6G fronthaul networks will interconnect numerous wireless nodes, while also facilitating high-speed communication, precise positioning, and environmental sensing capabilities. To enable coordinated operations among these distributed nodes, achieving a high level of temporal and frequency synchronization is paramount. Moreover, with escalating communication speeds, the data load for high-speed receivers escalates dramatically, intensifying the computational burden and power consumption associated with conventional multi-sampling and intricate digital signal processing techniques.
