Hello all,

I am using gnuradio 3.7.1. I am currently working on ofdm examples. In
tx_ofdm.grc, we generate CRC32 bit sequence and check the same in
rx_ofdm.grc. But in rx_ofdm.grc, the default option that is used is
Generate CRC32. When I select the Check CRC32 option, I do not observe
any output.
Why do we generate CRC32 again at the receiving end? Aren't we supposed
to "Check" for redundant bits?
