Hi,
I am working on a SISO link between two USRP2 based on OFDM. After trying
the different examples available I am stuck on a warning that comes up over
and over and I don't know how to solve it. I know it can be a pretty simple
question but I've already checked the mailing list and I saw that the
typical warning experimented by other people is due to the fact that they
have an error in the configuration of the sample rate. It's my
understanding that only integer divisor rates of the master clock is
possible. (100Mhz/decimation = sample rate). Well, I think that my problem
is not this one, because I am using a frequency of 1M. This is happening
only in the transmitter side, in the receiver USRP2 I don't get any problem
with the same sample rate configuration. I don't know if it is a hardware
problem or it is maybe a compatibility problem. I'd really appreciate your
help! Thank you in advance.
This is the message shown in the terminal:
