If this helps, you can precisely time transmit packets using stream tags. If you know the time when a transmit occurs, you can intelligently mute your receiver. See notes in uhd_usrp_sink.h
Also, it has just occurred to me that my stream selector block does not forward stream tags. - Mental note to myself. -Josh On 02/13/2012 12:04 PM, Zhonghua wrote: > Hi all, > > I applied Josh's new block "stream_selector", it is a great selector > which allow to set dynamic path without stop flow.
