I added a feature to the modem, where the user can specify the center frequency of the modulator and demodulator separately.
For example, in FM you might want to use 1 kHz instead of 1.5 kHz for a lower modulation index. Or over a wire, you might want to send full-duplex. The TX filter is also tuned to the modulator setting. I also modified the ofdm_mod and ofdm_demod to use this feature. Also I changed the code to use a version of getopt, and made them look like Unix filters. Example: ofdm_gen_test_bits --frames 100 --ldpc | ofdm_mod --ldpc --txbpf | ofdm_demod --ldpc --out binary.dat --log octave.txt Steve _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
