Hi all, I'm implementing new multi-user BPSK demodulater in gnuradio. I have good experience with OOT modules, etc.. If I want to understand some functionality of existing installed gnuradio file (provided by GnuRadio) by printing values of some variable, I can edit corresponding C++/Python file i

[Discuss-gnuradio] Two USRP B210s with Octoclock-G

2016-09-06 Thread Samith Abeywickrama
Hi all, I'm going to implement MUSIC(Multiple Signal Classification) algorithm to find Angle of Arrival of signal using two USRP B210s. Therefore I have 4 antennas. But I need to synchronise my two USRP B210s. May I know that can I use Octoclock-G with my USRP B210s without any problem? Thank you

Hi, I am confused with 89dB tx gain of USRP B210 and what is the meaning of 89dB gain? How this value relates to maximum output of 50mW in B210? Because this value is too much high, as a example: If the RF output power of AD9361 agile transceiver is -29dBm and after we apply 89dB gain, transmit po
