For the UHD performance issue, which model usrp? The following applies to usrp2: Was the bad performance on a transmit + receive application? There was an issue where if receive was not keeping up, the transmit flow control could be hampered; this is fixed on next branch. Or was it receive only? And in any case did UHD print and warnings about buffer sizes? Because it needs sysctl permission to allocate a large enough receive buffer. -josh > > Cheers, > > > Veljko > > > On Tue, Jan 11, 2011 at 9:26 PM, Guanbo <gbzh...@gmail.com> wrote: >> >> Hi, >> >> I was looking for the source codes through the list. >> And I got one from Veljko from UCSB, who are very nice to share his codes, >> "ofdm_example.tar.gz" >> The codes are attached. >> Given the enough gain in TX and RX, you can see the output result at RX. >> >> Guanbo >> http://old.nabble.com/file/p30650478/ofdm_example.zip ofdm_example.zip >> >> >> mrahaim wrote: >>> >>> >>> Hi all, >>> >>> Does anyone know of any updated OFDM benchmark code that is modified to >>> be run on a USRP2?
