Outline Why Future Wireless Telecommunication Systems Require Flexibility? What is the Software Defined Radio (SDR)? Universal Software Radio Peripheral (USRP) in the context of SDR Project Goals Progress and Future Steps

Why Future Wireless Telecommunication Systems Require Flexibility? Implement multi-standard solutions Enable legacy systems Allow upgradable solutions during lifetime Facilitate introduction of new services Reduce of production costs Speed-up time to market Optimize performance after recognizing operational environment during run-time

What is the Software Defined Radio (SDR)? SDR is a radio communication system that replaces some dedicated hardware with software on general computers or embedded systems Due to the software implementation, SDR is characterized by increased flexibility

USRP in the context of SDR USRPs are inexpensive, computer hosted hardware solutions for developing software radios through GNU radio. Two USRP generations (USRP -1 and -2) are available

Project Goals Achieve reliable transmission in a lower signal- to-noise ratio (SNR) environment Increase throughput, reduce error-rate Increase the system’s operational range

Progress and Future Steps (1/2) USRP-1 communication protocols have been modified to be operable in USRP-2 Interoperability between USRP-1 and USRP-2 has been achieved.

Progress and Future Steps (2/2) Evaluate system performance in different operational scenarios (e.g. line-of-sight, scattering environment) Improve physical layer algorithms (e.g. synchronization, channels estimation)
