(Now you can find “LTE-Cell-Scanner OpenCL accelerated (new)” in this page: http://sdr.osmocom.org/trac/wiki/rtl-sdr
And see latest progress: Whole 20MHz config LTE signal is decoded by HACKRF 19.2Msps with ASN1 SIB parsed
Here is my application.
Hi Administrator,
May I apply that if you can add my improved LTE Cell Scanner (https://github.com/JiaoXianjun/LTE-Cell-Scanner) to the list of APPs at http://sdr.osmocom.org/trac/wiki/rtl-sdr
You may have found track of improvement in this mail-list. The main new features are:
-
TD-LTE support; (Original one only support FDD mode Cell)
-
external LNB support. Just like the method of “NRF24-BTLE-Decoder”, external LNB can be added to extend band of rtl-sdr because most of TD-LTE frequencies here are above 2GHz. But external LNB breaks strict relationship of carrier-timing offset which is a basic assumption in the algorithm of the original one. Algorithm is improved to support this feature which make it work in many TDD bands locally.
-
OpenCL acceleration which accelerates speed of Cell Scanner much.
-
Capture and reload rtl-sdr raw uint8 bin file
-
Multiple tries at one frequency point to increase detection probability.
-
manual gain mode
-
…
So many changes have been made, I think it is hard or heavy time cost for James Peroulas (https://github.com/Evrytania/LTE-Cell-Scanner) to review and merge back.
TDD is an important feature for Chinese users. Most released system here are TDD, FDD even hasn’t been released officially here.
So I think it would be good to mention this improved Cell Scanner somewhere, and it would be useful and interesting for people who wants to scan TD-LTE.
( Now I have decoded LTE RRC SIB message in DL-SCH successfully in the same repo by HACKRF. Some time in the future maybe SIB decoding will be made also for rtl-sdr dongle, because I found that some SIBs are narrow band also (6RB, similar/like PBCH) and located in fixed frequency)
