Dear All,
I’m a graduate student and my research area includes wireless sensor
networks and signal processing.
I notice the lack of a absolute clock synchronization method in USRP
without cable or external input such as GPSDO.And the sync arruracy
should be as high as microsecond.This is crucial for some applications
such as localization,frequency hopping,relay communication,joint sensing
and TDMA.My target is to perform a block like this.
My current thinking is a timestamp based sync method.The general idea
is the following.
USRP A send several some data which contains the time stamp (called send
timestamp) when itself was send.USRP B receive the data and record the
time stamp (called received timestamp) when it was received.After
demodulation of the data,B get the send timestamp.With these two
timestamp,B can do some signal process to reach absolute clock
synchronization.
And now the problem is that I need a mentor.If you are interested,
please contact me.
Thank you in advance.
Best,
ZG
Hi Gong Z., (and other interested students),
you don’t need a mentor to put in a proposal for GSoC.
This is how it works:
- You write a proposal and submit it to GSoC
- We consider all proposals based on their quality, impact on the
project, feasability (and, let’s be honest, what we think is cool) - If a proposal is accepted, you will have a mentor. We’ll take care
of that.
Now, back to your idea. Because you’ve brought up your own project,
(and that’s a great thing, nothing more important than initiative in an
open source project!) there’s no default person to discuss it with, and
the only other way is to discuss it here, on the list.
As I’ve written before (off-list), I’m not 100% clear what your project
entails. You should to the following: Think about what exactly your
project should look like, what your milestones and deliverables could
be, specific examples for scenarios where your tool would be useful, and
how it justifies 3 months of full time work.
Then bring that back up in this thread.
On a side note, I’m happy that you’re interested in participating in
GSoC, but you would have helped everyone if you had brought up the idea
earlier!
