Hello everyone,

I implemented a burst transmission between two USRP N210. The transmission and the packet receiving works well, however I'm facing the following problem. From the reception side, I notice that after the packet receiving, the sampling signal does not come back to the ambient noise immediatly. It takes few milliseconds (about 40 ms) to come back to "0". It's like if there is still a signal transmitted after the real packet transmission. It may be a problem when you want to receive many consecutive packets with few space between them

I suppose that it comes from an hardware problem when the signal is put on the baseband ? Does that deal with the LO leakage ? What can we do to avoid this additional signal ?

Thanks,


Raphaël
