Re: [Discuss-gnuradio] overrun problem on gr-sounder project

[Yan Nie]

Hi Johnathan,

Thank you so much for the response on the suggestion of BPSK modulation implementation. I still have some questions on FPGA configuration and USRP baord:


1. What signal on the input of the receiver side (rx_a_a and rx_b_a) in gr-sounder application? (should the 12-bit signal be the amplitude of the received signal, which corresponds to the amplitude the usr provided?)


2. How does the tune() function work? Does that tune the signal after ADC, by creating a analog daughterboard? or it tunes the signal on the LFRX daughterboard  before ADC?


Thank you so much!


Regards,
Yan
