Despite the NodeB's best efforts, the transmissions from the mobiles will
not arrive at the NodeB at precisely the same time. The timing offset for
each mobile needs to tracked. The best way to do this is to correlate
against each mobile's scrambling code.
If, in Miguel's case he's trying to recei
Michael is correct. before demodulation the received signal should be
correlated. Michael, you said UMTS using scrambling code to do the
timing recovery. But the scrambling code is to distinguish MS in the uplink,
each MS use different scrambling code so I think the correlation
shouldn't be related
Hi Miguel,
You're correct that the rake receiver combines multipath effects. If there
is little or no multipath then a rake receiver is not necessary.
However, in any real world system a receiver needs to track timing offset
with respect to the transmitter. To do this the receiver needs to correl
Hi,
I am dealing with a UMTS uplink receiver implementation with USRP N210. I
have some general questions that I hope that someone can answer:
1) Is it completely necessary to implement a rake receiver? I have been
reading quite a lot about it, and it seems extremely complex because it
needs cha
