[Discuss-gnuradio] Need some help/advice
Hello, I finished to setup the receiver for my modem I have to build. Because it is based on the atsc-stuff I need a sample to test it. Is someone able to send me some data that is not processed by the atsc receive chain, which I can use for testing? Because there is still a problem with my transmitter I'm not able to generate my test data. Maybe anyone has an idea to fix my problem. When running the graph I get the following error message: Traceback (most recent call last): File "atsctransmitter.py", line 11, in import symbolmapper ImportError: /home/benedikt/gnuradio/programme/symbolmapper.so: undefined symbol: _ZN13gr_sync_block8forecastEiRSt6vectorIiSaIiEE Any help would be kind.

[Discuss-gnuradio] ATSC at the code repository
Hello, beside trying to solve my still existing problem to build wxgui I tried to set up the atsc transmitter/receiver as listed in the README.signal_flow, but I'm not able to find several blocks. I couldn't find GRWeaverModHead VSB modulator and GRWeaverModTail VSB modulator. The following question is, if I can use the "standard" mapping block from gnuradio, or there is a special block for atsc. Searching the mailing list I found a thread discussing to port the stuff to version 2.x/3.x. Did that happen? Can anybody help?

[Discuss-gnuradio] Question about Modulation
Hi at all, during the work on my diploma thesis I have to deal with Gnu Radio to set up a baseband modem. Now I've got a question: Is there a good place to find available modules for modulation or coding ? If there ist a place, maybe anyone can give me a hint where to find. Thanks for your help!
