[Discuss-gnuradio] OFDM Carrier allocator

[Germano]

Hi there,

I am trying to implement an OFDM transceiver, based on the existing GNU 
Radio OFDM blocks, for a cognitive communication system.
How can I update the "occupied_carriers" mapping (turn on/off carriers) 
while the flow-graph is running (in the carrier allocator and other 
occupied_carriers dependent blocks)?

regards,

Germano
