Hi,
I am trying to transmit and receive a .png file through OFDM (Block diagram
attached). The file size is only 1.5kB. While running I am getting the below
warning & error in console. Can someone point out the reason behind the error
and what I am doing wrong. I am a beginner and just started to learn the
Gnuradio from tutorials.
