Notes

BPSK

 

  • Set threshold phase shift, below that is a 0, above that is a 1

  • Modulate and demodulate

  • Implementation:

    • SDR (mostly software)

Raised Root Cosine Filter



  • Used to shape the pulse and response, only look at one part of the spectrum

  • Pulse shaping

  • Implementation

    • Probably SDR

Sinc function

 

  • A square in time domain is sinc in frequency domain

  • Infinite bandwidth

Resources

 

  • Dr. Kim of the ECE department

  • Dr. During is good at digital signal processing

  • Dr. Cracraft or Dr. Wheeler for analog shaping

Next steps

 

  • Find the SDR

  • Find the implementation

  • Figure out how we want the data to be brought down

 Action items

@Timothy Ausec DANESH BUG

 Decisions

  1. SDR that we have will have to be programmable
  2. SDR that we have better be able to bring UHF and VHF down to 0 (base band)
Looking for labels? They can now be found in the details panel on the floating action bar.
