Re: [Discuss-gnuradio] Link libraries to a OOT block

Thanks for the tips, I did get this to work after digging further into the CMake files. I made the static archive work, but it was ugly (recompile with -fPIC, linking with --whole-archive). Changing the build for the the library to produce both an archive and shared library and using the shared

Re: [Discuss-gnuradio] Install: qa_volk_test_all fails on armv7

2013-12-11 Thread Monahan-Mitchell, Tim
I am wondering if the QA failure is relates, to the use of the hard float ABI. For me, whenever I have tried to specify hard or soft float ABI, cmake fails. If I don't specify it, it just works... I'm switching my OE builds to armthf now so I can compare my results with Tom's. I'm

Hi, In gr-lte/37grc are all the needed GRC flowgraphs. LTE_flowgraph_top_level.grc is the one you eventually want to execute. When you first open 'LTE_flowgraph_top_level.grc' probably most blocks are missing. This is because all the 'hier blocks' are not compiled yet. Just open the other

[Discuss-gnuradio] Minimum amount of data to trigger WX GUI Scope Sink? and Ch 1 vs. Ch2 with Ch 3 vs. Ch 4

2013-12-11 Thread David Halls
Hi, I am using WX GUI Scope Sink, and I have set the sample rate = 1M, same as the USRP. It seems that a minimum number of data points are required before anything appears on the plot - is that correct, and how can it be adjusted? Also, I am looking at constellations, using the XY mode to show

[Discuss-gnuradio] Bit error rate test

2013-12-11 Thread Henry Jin
Hi I tried to use digital_bert_tx.py and digital_bert_rx.py to test the BER performance of different modulations. The command I use is ./digital_bert_tx.py --tx-freq=5.1e9 --tx-gain=30 -S 8 --mod-code=gray -m bpsk. The results for BPSK is good enough. When SNR is above 20, the BER is around
