2017-01-07 Thread adrian . perez . portero
I have been trying to incorporate BER measures in a more complex flowgraph that includes OFDM. I created a basic example to understand it better, but to my surprise when I run it, it stops after 2 seconds approximately. The interface is working, but the FFT Sink and BER Number Sink are stop

[Discuss-gnuradio] Dynamic OFDM carrier allocation

2016-11-28 Thread adrian . perez . portero
Hello, I am currently implementing a system where a receiver monitors the channel, senses the non-allocated OFDM carriers, and transmits through the gaps. I have created a block that lets me estimate those gaps in the spectrum, but I have several doubts about how it interacts with the res
