Hello, I just got back from the ARRL/TAPR DCC this weekend, and got excited about experimenting with codec2 and fdmdv all over again. :)
I want to try some experiments with an OFDM modem and the HF channel simulator, I'm trying to run the latest Octave code in the codec2-dev directory, following the directions in README_fdmdv.txt and running under Octave 4.0. In short, I am having all kids of issues. I am getting errors if I try to run fdmdv_ut from Octave - the first thing I get is that Nc is undefined. I found a block of stuff at the top of fdmdv.m which is "if 0"d out. If I put that back as a guess... Then I got another issue - needed to "pkg load signal" to find fir1... Then, I am having some other problems with get_test_bits and a missing value for current_test_bit...i defined that... Finally, I am having issues with tx_filter's function signature. Am I doing something very wrong? I think I remember that I got this all running a couple years ago. FWIW I also tried fdmdv_ut_coh.m but got errors immediately about missing bits_to_qpsk function... I apologize if I'm doing something stupid! Thanks, Frank Palazzolo NQ8N PS I do have all the C code building with CMake just fine.
