Table of contents Conclusion March 2006 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

Theoretical PER performance over AWGN channel March 2006 Theoretical PER performance over AWGN channel To Do: Give reference to presentations and textbooks Hach, Lee

15.4 DSSS over diffuse exp. model according to 15-04-0337-00-004b March 2006 15.4 DSSS over diffuse exp. model according to 15-04-0337-00-004b Trms EbN0 @PER=1E-2 100ns >22dB 200ns 300ns >23dB 400ns >27dB 500ns >40dB 20 bytes per packet Hach, Lee

15.4a CSS, 1Mb/s over diffuse exp. model March 2006 15.4a CSS, 1Mb/s over diffuse exp. model Trms EbN0 @PER=1E-2 100ns <17dB 200ns <15dB 300ns 400ns 500ns Hach, Lee

Comparing the numbers March 2006 Trms 15.4 DSSS EbN0 @PER=1E-2 15.4a CSS Difference 100ns >22dB <17dB > 5 dB 200ns <15dB > 7 dB 300ns >23dB > 8 dB 400ns >27dB >12 dB 500ns >40dB > 23 dB Hach, Lee

March 2006 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
