Description
Eray Güven, Louis Thivierge, Jean-François Frigon, and Güneş Karabulut Kurt demonstrate a relay scheme that pushes wireless fronthaul links into the sub-terahertz range for future networks. Mobile base stations need fat pipes back to the core, and the highest frequencies offer the bandwidth. Their extend-and-forward design lifts signals to those bands through repeaters rather than fiber.
The team models how phase noise corrupts symbols across linked hops, comparing synchronized and unsynchronized chains. On a testbed at 180 gigahertz built from software radios and frequency extenders, the synchronized setup delivered error-free user data at modest signal quality. The unsynchronized chain hit an error floor. Synchronization, they show, is not optional at these frequencies.
