The OFDM receiver is geared towards packetized data. It might work, but you'd need: - A synchronization algorithm - A better equalizer - A definition for the packet format.
For DAB the pi/4-dqpsk is differentially encoded in time over all subcarriers, with a pilot symbol over all subcarriers in the beginning, so no equalizer is needed really.
More code from a diffent project: https://github.com/andrmuel/gr-dab - that won't work out of the box for 3.7, but there is code. J
