Application for an URLLC modem: Industrial automation. Source:


Applications like factory automation, remote surgery, or vehicle control require extremely low latency connections, which also have to be very reliable at the same time. So far this has only been possible using wired connections, but the Ultra-Reliable Low-Latency Communication (URLLC) extension to 5G aims to provide a wireless option. The goals include 99.999% reliability and 1 ms end-to-end latency at the same time. This only leaves about 70-140 μs for the entire digital signal processing, compared to 4000 μs in LTE.

Project Description

We're currently building a FPGA-based testbed for 5G URLLC. During a typical project you can implement a key building block for the system.

Currently avalaible Projects:

  • Come up with a low-latency architecture for the processing of the equalized symbols: Selection, demapping, descrambling and accumulation. After that you will implement your hardware accelerator and verify that it works correctly.

Status: Available

Looking for Semester/Master students
