Re: [Discuss-gnuradio] LTE & LTE-Advanced using GNU Radio
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. 2011/8/17 Alexander Chemeris > Thank you, I will try. > > Do you know what flavor of LTE do they implement?

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?

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.

This link is for download. https://twiki.eurecom.fr/twiki/bin/view/OpenAirInterface/GetSources 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.

Re: [Discuss-gnuradio] LTE & LTE-Advanced using GNU Radio
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.

Re: [Discuss-gnuradio] LTE & LTE-Advanced using GNU Radio
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.
