Open source speech codec designed for communications quality speech between 700 and 3200 bit/s. The main application is low bandwidth HF/VHF digital radio.
When the Octave simulations and OTA testing have shown the new modem waveform is useful, port the modem to C. Note that for a complete Low SNR FReeDV mode we also need a candidate speech codec (WP2000). This WP deals only with the C port of the modem code alone
[ ] Shall we still use the Octave->ofdm_xxx->freedv_xx workflow?
[ ] define ctests we need to pass
[ ] obtain/develop a new LPDC code that includes payload and txt bits, so that txt bits are now protected (alternative to reliable text system).
[ ] perform port
[ ] review code
[ ] review corrections
[ ] PR is merged
Reviewers: David and Mooneer
Deliverables:
[ ] list of ctests and pass criteria
[ ] ofdm_xx.[ch], ofdm_xxx.c ported and passing ctests
