Lyerns -

The "timing error" here is the offset of the peak of the correlator output from zero.  For a RACH burst, this offset is dominated by the round-trip propagation delay between the BTS and handset.  For other burst types, this offset is equal to the error of the timing-advice control loop.

Hi!
I'm reading the source code of Tranceive and TRXManeger. But what does "timing error comes in 1/256 symbol steps because that fits nicely in 2 bytes" mean?where is this "timing error" from?
Thanks!
