Congrats! Hey, have you ever thought about re-visiting your digital voice modem? I was thinking that now with codec2 you could add a DBPSK pilot carrier on the left, and then 18 OFDM carriers. I'm thinking 32 bits at 50 baud (even and odd synced to pilot) for a 64 bit vocoder. 1300 mode + 300 bits FEC works at 64 bits. Keep those FPGA's humming !
Hi Steve, I think I will leave the HF stuff to others. There has been some talk recently of using codec2 in conjunction with narrowband digital tv. Thanks, the ward was most unexpected.
Well done to Charles and the team and thanks for all the time you've spent on the project.
ReplyDeleteMuch appreciated Ian.

ReplyDeleteoops, I mean 16 carriers...
