In this lab, students will create a DSSS signal with a simple message and explore its characteristics in the frequency domain using the Emona Communications Board and NI ELVIS III Instrumentation. Students will also complete activities to understand how DSSS is recovered with a unique key, and why it is resistant to jamming and interference.
After completing this lab, students will be able to:
Generate a real DSSS signal using a simple message.
Describe the spectrum of a DSSS signal.
Discuss the recovery of a DSSS signal: what works, what doesn’t.
Discuss the resistance of DSSS to jamming signals.
