Contents Background and Objective Spread Spectrum Theory Introduction Labview Simulation USRP Manipulation Application and Advance
Project Background Originally military used Reliability Security Broaden application Computer Network Wireless Communication 3G
Project Process Explore the theory Digital Communication Use the software and hardware to experiment and simulate Labview USRP Application and Advance Dynamic spectrum access Tamed spread spectrum Application
Theory Basis Shannon Theorem When S/N is very small 0.1
Direct Sequence Spread Spectrum
Labview Programming With USRP Manipulation Labview Graphic programming software developed by NI. USRP: A hardware to make PC work as software radio with large bandwidth
ASCII The real transmission PSK Message transform Packet form Synchronization and checkout Modulation and spread PN PN
Evaluation Model Transmission Gain ?? ?? G = ?? ?? Error rate
The evolution System bandwidth make the increase in the number of jamming signal in the front-end of receiver Dynamic spectrum access The channel capacity is limited Tamed spread spectrum
