[Discuss-gnuradio] OFDM Carrier allocator

2014-02-24 Thread 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

With the stock behaviour, it's not possible. If you want to change the
block, I recommend passing the new carrier allocation as a tag, check
for that at the beginning of work() and re-populate the corresponding
attributes.
