Forum: GNU Radio Echo Cancellation for USRP?

Hello Gurus,

My duplex system is using only one frequency but different time slot to 
let
two USRP exchange data. But from the observed receiving waveforms, I 
found
that the received signal is very high and causes the jitter if the 
receiver
keeps receiving its own transmitted signal within its own time slot. 
This
jitter could impact the subsequent time slot for other transmitter, by a
tail.
I want to add something like echo cancellation to remove this 
side-effect.
Before that I am wondering if any has done the similar thing. Also,  I
don't think the pure software method can solve this problem. Do we have 
any
hardware support for this transmitting close loop issue?

Best Regards,
