2. Table of contents • Theoretical BER performance over AWGN channel • Theoretical PER performance over AWGN channel • 15.4 DSSS over diffuse exp. model • 15.4a CSS over diffuse exp. model • Conclusion Hach, Lee

3. Theoretical PER performance over AWGN channel To Do: Give reference to presentations and textbooks Hach, Lee

4. 15.4 DSSS over diffuse exp. model according to 15-04-0337-00-004b 20 bytes per packet Hach, Lee

5. 15.4a CSS, 1Mb/s over diffuse exp. model Hach, Lee

6. Comparing the numbers Hach, Lee

7. Conclusion • 4a CSS gives 2 dB theoretical improvment of performence over 15.4 DSSS • 4a CSS gives between 5 and 23 dB improvement of performance in multipath environment Hach, Lee

8. Thank you! Hach, Lee
