Re: [Discuss-gnuradio] Microwave Link Demodulation

One way I check for bottlenecks it to run 'top -H' and watch the various threads. If you see any one thread pegged at 100% then it needs to be optimized. At least that's my method :) On Mon, Aug 29, 2016 at 9:46 AM, Ihab Zine wrote: > Hi Marcus, > > I have been through the GNU RADIO tutorials

[Discuss-gnuradio] PMT Oddities

I noticed today that the is_dict and is_pair checks are not appearing to work properly. Here is an example that shows the issue: [code] #!/usr/bin/python import pmt def print_pmt(dictVar): print 'isPair:%05s, isDict:%05s, isTuple:%05s => %s' % (pmt.is_pair(dictVar), pmt.is_dict(dictVar),

Martin, Was that done on purpose? Thank you for the link! I hadn't thought about checking that way. Thanks! -Dave On Tue, Nov 22, 2016 at 5:08 PM, Martin Braun wrote: > Dave, > > pairs pass is_dict(), which is possibly the root cause here. See also: > https://gi

Re: [Discuss-gnuradio] PMT Oddities

I ask because it feels like a bug. Things like ((a . b), (c . d), (e . f)) are definitely not pairs (assuming a pair is 2 elements) and (in my opinion) should not return true for pmt.is_pair(). On Tue, Nov 22, 2016 at 5:12 PM, Dave NotTelling wrote: > Martin, > > Was that done o

[Discuss-gnuradio] Max PMT Size

I seem to remember asking this question once before and being told that the only way to increase the max size of a PMT object is to set a define in a header file before compilation. Is this size limit only applicable to the PDU to Tagged Stream block? Can a PMT output to another PMT input be what

Re: [Discuss-gnuradio] PMT Oddities

in dict_keys return _pmt_swig.dict_keys(dict) RuntimeError: pmt_car: wrong_type : () [/output] The first call to dict_keys(a) returns the last element in the dictionary. The second call errors out. Both should error out correct? On Fri, Dec 9, 2016 at 9:11 PM, Dave NotTelling wrote: >

[Discuss-gnuradio] fft_filter_ccc Output Buffer Size

I am trying to use the FFT filter in some c++ code and I'm having issues with seg faulting. The code below will work, but only because the output buffer is twice as large as the input buffer. It doesn't have to be twice as large, but it does have to be some number larger than the input buffer. Wh

After some more research it seems that this is an issue of not having an even multiple of input samples to taps. For others, here is where I found the answer: http://www.dspguide.com/ch18/2.htm On Fri, Feb 10, 2017 at 11:19 AM, Dave NotTelling wrote: > I am trying to use the FFT filter in s
