Hi,
I’m a beginner using GNU Radio Companion.
I have a simple flow graph consisting in a vector source, a PSK Mod, a
throttle and USRP sink.
The problem is that I’m transmiting a lot of noise because when I run
the graph the CPU works up to 186% which adds a lot of noise to my
signal. This is way too much considering the flow is very simple and I
have a throttle block. Even when I lower the sample rate to 10kHz the
CPU is still over 100%.
Also, GRC is supossed to separate the blocks into separate cores, but in
my case, the entire program runs in just one core. This wouldn’t
completely solve the problem, but it would help a lot.
Is there any way to control this?
Thank you very much
