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:

- that won't work out of the box for 3.7, but there is code.
