Goal Recap:

  • Achieve Directional Modulation with a Metamaterial Antenna Array.

  • Test our system in the anechoic chamber on Busch.

4 of 6

Weekly Progress:

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