I would assume GNUradio's OFDM is mathematically identical to Hydra,
have you tired finding what settings ( Channel spacing, FFT size,
Number of sub-carriers, Sub-carrier modulation scheme, symbol length,
guard interval, Sub-carrier spacing, and FEC ) hydra uses and setting
GnuRadio to that. It should yield identical throughput.
