Hi,
Thanks for the reply! For the moment, if I upgrade to latest version of UHD, my programe does not work properly(lots of LLLLLL). Therefore I could not tell if it helps or not. One burst is about half millisecond. I thought it is long enough, is it? Regards! Liang ________________________________ 发件人: USRP-users <usrp-users-boun...@lists.ettus.com> 代表 Marcus D.

Then I tried to assign RX2 as receiver anteena and I get approximately 20dB stronger TX signal with almost same code. The main difference is: for two anteena case, in each subframe TX send one burst, while in one anteena case, TX just sends zeros instead of stoping transmission. The installed uhd version is 3.9.7. Does anybody know what could possibly be reason for this? And how could I achieve full power with single anteena TDD system? Thank you! Are you able to upgrade to a newer UHD version? Does that help? How long are your bursts? Is it possible that they're shorter than the switching time?
