Re: [Discuss-gnuradio] OFDM Channel Equalisation not unity for perfect channel

2017-05-07 Thread Justin Hamilton
Hi again, My current suspicion is that there is a triggering delay produced by the *Schmidl & Cox OFDM Sync* block that isn't accounted for by the *delay* block currently running in parallel to it in the flowgraph (delays samples going to the header/payload demux until the trigger point is found i

Ubuntu 16.04. I followed the notes for the nvidia install. Got me past the incompatible headers. Would be cool to steal the cmake opencl magic they use in gr-phosfor so it picks up the right includes and whatnot paths. Anywho, now I get: home/anon/gr-clenabled/lib/clFilter_impl.h:26:24: fatal erro

2017-05-07 Thread Justin Hamilton
Hi everyone, I've been working on a coded-OFDM system (looks similar to the standard OFDM flowgraphs) and have come to the stage where I am trying to improve channel estimation by implementing LS, STA and comb pilot interpolation methods similar to gr-ieee802.11. If I follow the default technique

Hi Anon. I set it up for 1.2. The biggest gotcha I've run into in the build process is missing the cl.hpp file, but how to get it can vary by OS. There's some setup notes in the setup_help directory for debian and Ubuntu that may help you out. What OS are you running it on? On Sun, May 7, 2017

Neat. What opencl implementation are you building against? I get errors related to _svm_ parts of code. I.e. cl_device_svm_capabilities was not declared in this scope. Trying to use the Nvidia cuda sdk, just downloaded from their developer site (ver 8.0). On May 6, 2017 8:59 AM, "Ghost Op" wro

Hello, I'm new in gnuradio and maybe don't know some obvious things... But where is a bugtracker? I found a link https://gnuradio.org/redmine/projects/gnuradio/issues in the FAQ, but it redirected me to the https://gnuradio.org and it's strange, I think ;-) _
