Deep dive into OFDM modem algorithms, use math and simulation to seek improvements over FreeDV 700D/E. After the initial iteration, seek out a suitable reviewer for review.

  • Outline key requirements
  • Model for voice link
  • Equalisation
  • Multipath
  • Intersymbol interference
  • Timing estimation
  • PAPR reduction
  • Acquistion
    • Coarse timing
    • Coarse freq
    • UW post processing
    • state machine
    • Fine freq estimation and tracking
    • CPU load estimates
  • Consideration of single carrier (removal of 300 baud limit)
  • Automated tests to prevent bit rot of simulations

Refs

  1. WP4000 - Study task list #17
  2. freedv_low repo for the study

Deliverables

  • Latex document
  • Octave simulations
  • README summarizing how to run simulations and build Latex doc
