Matt, Thanks for verifying the data rate calculation!
I tried the other solutions that you suggested, namely, *- increasing the data rate by a factor of 2 or 4 *It works. * - modifying the OFDM code to widen the search range* - How do I widen the search range ? Should I be looking in the "ofdm_sync_" blocks in "blks2impl" folder ? If yes, which synchronizer is currently used with ofdm_examples ? *- locking the usrps to a common reference *My usrp2s are located wide apart so I guess this solution is not practical. Besides, this confirms that the problem is somewhere in the USRP2 board, right ? (as I tried swapping the daughter cards & firmware with the working pair) Thanks, Srinivas On Sun, Feb 14, 2010 at 3:25 AM, Matt Ettus <m...@ettus.com> wrote: > > That formula will give you the number of occupied tones per second.
