[Discuss-gnuradio] OFDM and SNR EST

Dear all,

we are trying to use the block digital_mpsk_snr_est in an OFDM flowgraph.
We think that the right place for the snr_est is after the ofdm_frame_sink however we have the following error:

itemsize mismatch: ofdm_frame_sink(27):0 using 1600, mpsk_snr_est_cc(28):0 using 8

(consider that we have 200 occupied tones and hence 1600 is 200*8)

Do you have any idea?

Thank you
