HI,
I am trying to see communication between two usrp's using tunnel.py on two virtual ports gr0 and gr1, so i am trying to run tunnel.py on 2 usrp's in my lab using gmsk. I am unable to receive packets in the receiver. so i was trying to debug. But i was unsure of certain things.
1. There is no interpolator option. so I do not know how is sampling occuring, i only see it says usrp running at 64 MHz. can somebody show me a link or explain the calculations behind obtaining samples per second given a user set data rate, modulation,carrier threshold and amplitude level.
2. How do i know how to vary the gain and carrier threshold. Because increasing too much gain will put the setup in nonlinear region.
