Hi, Sebatian Sorry for my insufficient introduction. I have written a more clear version of README here <http://sdr-x.github.io/LTE-Cell-Scanner%20supports%20bladeRF%20now%20%28LTE%E5%B0%8F%E5%8C%BA%E6%90%9C%E7%B4%A2%E7%A8%8B%E5%BA%8F%E6%96%B0%E5%A2%9EbladeRF%E7%A1%AC%E4%BB%B6%E6%94%AF%E6%8C%81%29/> to show the concrete commands and outputs.
Basically, the program read real-time A/D samples from SDR hadware (rtlsdr, hackRF, bladeRF) and perform full stack LTE physical layer processing (time-frequency synchronization, frame synchronization, channel estimation, channels demultiplexing, convolution decoding, turbo decoding, ASN1 parsing, etc.) to get MIB info in PBCH channel and RRC SIB message in PDSCH. It is based on James Peroulas's https://github.com/Evrytania/LTE-Cell-Scanner . I add some new features, such as TDD, OpenCL, external-LNB, hackRF, bladeRF, pre-search-algorithm, etc. You may find the evolution by digging my repo and searching internet. Also paste latest README here for your information: *0x01. basic method to build program* mkdir build cd build cmake ../ -- default for rtlsdr and OpenCL ON; OR cmake ../ -DUSE_BLADERF=1 -- build for bladeRF; OR cmake ../ -DUSE_HACKRF=1 -- build for hackRF cmake ../ -DUSE_OPENCL=0 -- disable OpenCL (See notes in later chapter) make CellSearch and LTE-Tracker program will be generated in build/src. Use "--help" when invoke program to see all options. (You may need some related libraries, such as itpp, fftw, libboost-, Curses, ... etc.) *0x02. basic usage (If you have OpenCL, make sure those .cl files in LTE-Cell-Scanner/src have been copy to program directory)* *0x02.1* CellSearch --freq-start 1890000000 (try to search LTE Cell at 1890MHz) output: ...
