thanks so much, I follow your direction, it's ok now. Now "make" and "sudo make install " all ok. But now I run: examples python hier_block_install_helper.py so many errors: like this: Block key "lte_pbch_demux_vcvc" not found Block key "lte_pbch_demux_vcvc" not found Block key

[Discuss-gnuradio] The use of scrambler/ descrambler blocks

2017-08-28 Thread mehtap özkan
Some years ago I implemented a scrambler block in FPGA for a transmitter. It produced an output every clock cycle. Now I try the GNU Radio scrambler/descrambler blocks. They work great if the data flows continously like from a Vector source or File. However if I have a discontinous source like a

Hi Marcus, i attached the flowgraph to this mail. The constellation Modulator places the tx_eob tag too early (sps*8/ ld(QPSK.arity()) ), which is fixed by using a oot-module, delaying it. Using BPSK instead of QPSK works fine, so I think the problem is located in the way using the

Sebastian What center frequency did you use? What RF cards are you using? Are you using coaxial cable,to connect transmit to receive or are you transmitting and receiving through an antenna? If you are using antennas please describe them. Cheers Bob Bob On Aug 26, 2017 12:12 PM, "Sebastian"

So, how did you install GNU Radio, and where? The output of `gnuradio-config-info --prefix -v` might help us. Best regards, Marcus On 08/28/2017 03:03 AM, w xd wrote: thanks sir can you explain it more clearly?sorry for not familiar with it. I just copy the "volk":(it can not work also) I

You most prominently need to *link* against libvolk. That requires you to add an appropriate target_link_libraries entry in lib/CMakeLists.txt On 08/28/2017 10:10 AM, Johannes Demel wrote: Hi all, I'm uncertain how to integrate VOLK into the 'gr-lte' CMakeLists file. I've just looked at

I believe you just have to add it to the GR_REQUIRED_COMPONENTS. Change: set(GR_REQUIRED_COMPONENTS RUNTIME FILTER) to: set(GR_REQUIRED_COMPONENTS RUNTIME FILTER VOLK) Ron On 08/28/2017 01:10 AM, Johannes Demel wrote: Hi all, I'm uncertain how to integrate VOLK into the 'gr-lte'

Hi all, I'm uncertain how to integrate VOLK into the 'gr-lte' CMakeLists file. I've just looked at some other modules. I ended up just adding the line 'find_package(Volk)'. This ends up in a 'works for me'. CMake finds 'VOLK' and I could just compile 'gr-lte' from a new github clone. Though,
