Demo: Soft-LTE: A Software Radio Implementation of 3GPP Long Term Evolution Based on Sora Platform (Best Demo Runner-up)

This demo shows an implementation of 3GPP LTE (Long
Term Evolution) [2] Uplink, using Sora high performance
software radio platform [5]. LTE is the state-of-the-art widearea
wireless technology and employs many cutting-edge
physical layer designs, including Turbo Coding, MIMO, SCFDMA
and OFDMA [3, 4]. This demo shows a LTE Uplink
implementation based on Release 8 3GPP 36 Series
specifications in LTE-TDD (Time Division Duplex) system.
Specifically, we implement the PUSCH (Physical Uplink
Shared Channel) physical layer in single user environment,
which provides a peak rate of 43.8Mbps with 20MHz channel
band. The whole implementation contains around 5,000
lines of C code and runs in real-time in a commodity general
purpose PC.
