Voice Communication with USRP through OFDM

GNU Radio
1

Hello all,

I want to make a test communication system with USRP for narrow band HF
range voice transmission and reception. Also I am interested in using
OFDM
scheme for that.

I need some guidance about what packages I should use for HF freq range
and
OFDM multiplexing…?

If someone could provide me any tutorial links for establishment of OFDM
and HF communication link with USRP.

Thanks in advance.

Start with setting up the OFDM Transmitter and -Receiver blocks using
random data. Make sure you’ve understood all the concepts along the way
(tagged streams etc.).

Once that works, I recommend using the vocoder blocks to generate
compressed digital voice data and pipe that into the OFDM codes.

Cheers,
