The Tick Programmable Low-Latency SDR System.

Software-defined radio (SDR) allows users to build flexible and configurable wireless communication systems. A number of SDR platforms are already available for use [3, 4, 5]. However, given the latest technology push (e.g., 5G, wireless edge computing) and user demand pull (e.g., low-latency VR/AR, realtime control on drones), today's requirements on SDR are different. Ideally, SDR systems should offer sufficient programmability and ensure high performance for both physical (PHY) and medium access control (MAC) layers. Unfortunately, it is hard to achieve both in the existing SDR systems.
