Security Programmable Metamaterial Antenna for Physical Layer Security

Week 8:

​

Prachi Patel and Dylan Turner

Introductions:

Prachi Patel

Goal Recap:

• Achieve Directional Modulation with a Metamaterial Antenna Array.

​

• Test our system in the anechoic chamber on Busch.

​

​

Weekly Progress:

• Solved our issue with precoding sync words.
• Replace zeros in the sync words with random symbols.
• Calculate G_Ѱo using S₂
• Multiply original symbols by inverse of G_Ѱo
• Ultimately the zeros are maintained.

Weekly Progress:

​

• Experimented with the USRPs that we’d be using with the antenna.
• Encountered many bizarre problems.
• Tests worked on SB2, but not on the on site USRP.
• Last packet being dropped.
• Flipping cable around had an effect. (Not a directional cable)

Goals for Next Week

• Continue experimenting with USRPs, then hopefully with the MTM Antenna.

​

• Follow some Vivado tutorials become more familiar with programming FPGAs
