Introduction to DSSS (Spread Spectrum)

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.
