Re: [Discuss-gnuradio] ofdm mod error
Marcus, I just saw i was still running a 32 bit installation of linux. I just removed my old installation and busy reinstalling a fresh Ubuntu 14.04 LTS. What instalation way is best? Installing by the sudo apt-get install command or just build my own version? best regards, Nick - Oorspronkelijk bericht - Van: Marcus Müller marcus.muel...@ettus.com Aan: discuss-gnuradio@gnu.org Verzonden: Maandag 24 augustus 2015 16:59:13 Onderwerp: Re: [Discuss-gnuradio] ofdm mod error The point is that what you're seeing is clearly a Python telling you that it can't find the crc32_bb module nor the constellation_psk object where they should be, on a proper installation of GNU Radio. This is not a problem of these examples, but of your installation; as Martin hinted, we need to solve that first.

Re: [Discuss-gnuradio] ofdm mod error
Patrcia, this looks more like you don't have GNU Radio properly installed -- these examples will work fine with a full installation of GNU Radio.

i've noticed that the digital_swig causes some error for both... looking at it, there is nothing inside the digital_swig.py file... is that ok? -- Posted via http://www.ruby-forum.com/. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] ofdm mod error
Patrcia, try the new OFDM blocks. I suggest starting with the example ofdm_loopback.grc and working from there to see how things work, Cheers, Martin On 17.08.2015 22:39, Patrcia Wonder wrote: Hi!
