LTE & LTE-Advanced using GNU Radio

Dear all,
Is anybody know if there is any work on LTE or LTE-A using GNU Radio? is
there already any code for LTE phy layer on GNU Radio? please provide me
any
information if there is one. thanks…

Adib,

I have started some LTE phy work. My long term plan is to develop it
using
GNU radio. However, most of it is currently in matlab and I need some
LTE
PHY test data in order to validate it. If anyone has any data
(specifically
recorded downlink I/Q data) it would be extremely helpful.

great Ben. so is this your PhD work? can it be shared? so you already
have
lte phy in matlab? is it your code? can it be shared? =) appreciate it
much
and thanks in advanced.

Adib,

This is work that I am just doing in some of my free time. It can be
shared, but currently it is not complete enough to be of any use. It is
code that I am writing and would be willing to share once it is further
along.

Hi,

We are also working on a similar project, developing physical layer
components of LTE-Advanced in gnuradio. We are in the learning process
of gnuradio, I look forward to have a mutually beneficial coordination
with you.

Ben,

Take look into our Matlab code for WiMAX (ostapenko-work branch),
there should be pieces helpful for LTE implementation:
http://code.google.com/p/wimax-scanner/

And as I mentioned earlier we invite everyone to join us and create a
single code base for 4G PHYs implementation - there are a lot of
common concepts.

A very late message :wink:

There is one open source LTE implementation in Eurecom, named as
OpenAirInterface
https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/WebHome

We are now trying to connect this with USRP by UHD.

Hi Lin,

I’m also looking into it right now, but I can’t find LTE-related code
in their downloads. Did you?

Anyway, please keep us updated with your progress, this is very
interesting.

This link is for download.

But the username seems not usable. You have to contact the server
administrator to get an account.

I downloaded the code. It has most of LTE funcitons, only few bugs and
mistakes which are not fully compatible with the LTE specification.

Our comment is: this is a very good reference.

I couldn’t find any contact information for the administrator or
anything on getting access. Do you know where I can find that
information?

Adib,

We’re working on an open-source implementation of WiMAX PHY. It’s not
exactly LTE, but they have many things in common, so we plan to do LTE
work. We invite everyone interested in 4G PHY levels to cooperate and
especially we’re interested in WiMAX and LTE.

To date we only have Matlab scripts, which can decode from I/Q samples
to DL-MAP, but we should start moving to C/C++ code very soon. This is
one more area where we would appreciate contributions.

Project is hosted at Google Code:
http://code.google.com/p/wimax-scanner/

Contact me if you have questions.

Yes, their approach to open-source is somewhat weird.

I downloaded the code. It has most of LTE funcitons, only few bugs and

Do you refer to L1 or L2 or L3 or all of them?


Regards,

At least L1, we spent a lot of time on checking the code’s compliance
with
spec.

I heard the RRC part is not completed.

Thank you, I will try.

Do you know what flavor of LTE do they implement? Is it something
which can be useful in Europe, or it’s only Chinese version of LTE?

What Eurocom is developing is a TDD system, but I don’t think they
develop
for Chinese version. Long time ago, when they developed the 3.84M chip
rate
TDD CDMA system they focused on TDD. So I guess the reason may be the
spectrum license that Eurocom has is a TDD one.

As for us, our target is a FDD LTE system.

Dear Adib
I have also started some LTE phy work using GNU radio.However, I have
not found suitable code for LTE phy layer on GNU Radio .
If you have any already code,Would you please give me some information
about your code .
Thank you for your help.
