srsUE is an open source software radio LTE UE. It is written in C++ and builds upon the srsLTE library. Running on an Intel Core i7-4790, srsUE achieves up to 60Mbps DL with a 20Mhz bandwidth SISO configuration. It works with the Ettus B2x0 and bladeRF frontends and has been tested against different commercial and open source eNodeB.

In this talk we'll explain the internals of srsUE, it's architecture, the threading design and the optimization steps taken to achieve top performance.
