2. General Information Senior Design Project May 11-18 Project Adviser: Dr. Aditya Ramamoorthy Graduate Assistant: Shizheng Li Team Members:  Alex Dolan  Mohammad Khan  Ahmet Unsal Project Website http://seniord.ece.iastate.edu/sdmay1118

3. Project Description Design a digital communication system using Simulink and USRP-2  Should work for different modulation schemes Implement simplified 802.11 MAC Test MATLAB Simulink’s versatility as a SDR platform

4. Project Plan Implement Physical Layer Implement MAC Layer Integrate the layers to form the network Test the overall system

5. Project Design Physical Layer Implement point to point communication Achieve reasonable bit error rates & transmission rates  BER = 10^ -4  Transmission rate= 50 kbps Implement digital modulation schemes  FSK  DBPSK

6. Project Design MAC Layer Implement MAC (Multiple Access Control) Layer for network communication Implement simplified 802.11 MAC

7. Current Status Currently working on  FSK (Frequency Shift Keying) Model  DBPSK (Differential Binary Phase Shift Keying) Model

8. Current Status MATLAB models work nicely (No frame errors) Noise reduction schemes on over the air models need more work

9. Current Status Also working on Error rate improvement tactics  Transmitting the same bit multiple times and decoding on the receiver side Image file transmission  Turning a binary image into frames and transmitting an image
