SRS is pleased to announce the release of their open-source software-radio LTE UE, srsUE. Written in C++, srsUE provides all network stack layers from IP to PHY and builds upon the existing srsLTE PHY layer library. Running on an Intel Core i7-4790, srsUE achieves up to 60Mbps DL with a 20Mhz bandwidth SISO configuration. The srsUE application and srsLTE library use a hierarchical, modular design with clean interfaces and minimal external dependencies to permit code reuse and adaptation. Modules ranging in granularity from dft blocks to full MAC-layer random access or HARQ procedures can be reused within flowgraph frameworks such as GnuRadio. For code and further details, see the github project pages: www.github.com/srslte/srsue. For support, please subscribe to our mailing list: www.softwareradiosystems.com/mailman/listinfo/srslte-users.

*Features* _PHY Layer_ LTE Release 8 compliant FDD configuration Tested bandwidths: 1.4, 3, 5 and 10 and 20 MHz Transmission mode 1 (single antenna) and 2 (transmit diversity) Cell search and synchronization procedure for the UE Frequency-based ZF and MMSE equalizer Highly optimized turbo decoder available in Intel SSE4.1/AVX (+100 Mbps) and standard C (+25 Mbps) _Upper Layers_ LTE Release 8 compliant MAC, RLC, PDCP, RRC, NAS and GW layers Soft USIM supporting Milenage and XOR authentication Some functions for RRC/NAS message parsing and security from OpenLTE project (http://sourceforge.net/projects/openlte/) _User Interfaces_ Detailed log system with per-layer log levels and hex dumps MAC layer wireshark packet capture Command-line trace metrics Detailed input configuration file Virtual network interface tun_srsue created upon network attach _Hardware_ srsUE currently supports Ettus Research USRP RF front-ends through the USRP Hardware Driver (UHD). Host sample rate conversion is not supported, therefore the hardware should support configurable clock rates. We recommend the USRP B2X0 range. -- ________________________________________________________________ Paul Sutton Ph.D. Software Radio Systems (SRS) http://www.softwareradiosystems.com +353-87-9813473 | [email protected] PGP Key ID: 3B4A5292 Fingerprint: B0AC 19C9 B228 A6EB 86E1 82B2 90C7 EC95 3B4A 5292 ________________________________________________________________
