Hi, I implemented OFDM receiver on USRP E110 using the OFDM receiver in examples in gnuradio's files 3.7
and I added to it a chain to create OFDM transmitter: random source, OFDM transmitter, channel model, throttle, USRP sink But when I executed the flow graph. It generated "UOOOOOOOOOOOOOOOOOO" and I got an error : FATAL: Missing a required length tag on port 0 at item #0 thread[thread-per-block[21]: <gr_block crc 32_bb (9)>]: Missing length tag. and tag debug didn't show anything. Have you an idea how to fix this error ? Thanks in advance
