2. 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

3. 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

4. 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

5. 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

6. 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

7. 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.

8. 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)
