Hi all,
These days I encountered the problem of usrp underrun .
The phenomenon is that I have two usrps, one is a sender and another is a
receiver, the modulation is dqpsk. If the data rate of sender is low , the
uU comes and the receiver lose lots of packet , and if the data rate of
sender is hi
Hi all,
At first, I use the benchmark_tx to send with usrp-a. After sending is
finished ,I use the benchmark_rx to receive on the same usrp and there are
another sender which is usrp-b.But I can't receive anything. The
usrp_source_c gives nothing.
If I reload the firmware of usrp-a, everything is
12 12

There are two aux_adc on one ad9862:aux_adc_a and aux_adc_b , but there are
four pins : aux_adc_a1,aux_adc_a2, aux_adc_b1 and aux_adc_b2. But what is
the input of the signal on these pins?
Thanks a lot.

hi all,
I want to use the read_aux_adc method to get the RSSI, but the results I got
seem meaningless.
1. Everytime I call the read_aux_adc, the result increases step by step.
2. No matter whether there is a sender, the result is the same.
Does anyone come up against this problem ?
Any suggestio
Hi all,
I want to read aux_adc of AD9862 to get the RSSI value.But when I read the
code of method usrp_read_aux_adc, I am confused.
The aux_adc of AD9862 is 10-bit. Why is the result of usrp_read_aux_adc
formatted as 12-bit.

Hi all,
I'm thinking about implementing non-contiguous OFDM with gnuradio. So I read
the ofdm codes of gnuradio. And I find the occupied tones concept in
gnuradio. Is it designed for non-contiguous OFDM? Or it is for other
reasons?
