sorry disregard previous mail
I
am trying to implement a multi-relay cooperative network using gnuradio
and USRP B200. I cannot figure out how to synchronize the relay
transmissions using GNU-Radio (without editing FPGA code or using
external clock source).
I created an out of tree module derived from the tags_demo example of uhd but i encounter a problem with the packet encoder.
my flow graph is something like
USRP source ---> tagging_block ---> DBPSK demod -->packet decoder --> encoder --> mod --> USRP sink.
when i attach tag debug block, i see that the packet decoder is not propogating my tags. Are their any substitutes to the encoder or is there any problem with my code which is attached. Any help would be very welcome. Thanks!
