[Discuss-gnuradio] power control when packets transmitting

[KC Huang]

Hi:
 
My recent research project focuses on how to implement CogNet on GNUradio platform. As u know, the concept of cognitive radio is that the parameters can be adjusted according to different situations. Such as controlling power, switching freq and modulation when the packets are transmitting. But I am not sure if GNUradio platform can adjust these parameters in the middle of tranmission. I searched previous threads and found that metadata structure can do that because of pipeline transmission. Are there any ways to adjust parameters without using mblock format because I don't think mblock is mature now?
 
I appreciate any suggestions!
Thanks!!
