Hello all, I am trying to create an OOT take a value from a Blob type in GNU Radio, and put it out on an output as Float Data type, I have tried the following: *x = pmt.dict_ref (pmt.car(msg), y, pmt.from_double(100)) #this is suppose to take "y" and make "x" equals the value of "y"* *z =

Re: [Discuss-gnuradio] Question on Samples/Symbols (sps) in "PSK Demodulation" tutorial.

2018-12-27 Thread Cinaed Simson
Hi Ashish - the short of it is: (samples/sec)/(symbols/sec) = samples/symbol If the bandwidth is complex, then samples/sec = sampling rate in MHz, and symbols/sec is the baud rate. There are lot of reasons why you would get into trouble by just by changing samples/symbol. You need to post

[Discuss-gnuradio] GNU Radio Enhancements: Worth a Look!

2018-12-27 Thread Martin Braun
Hi all, In case you didn't know: Like many other free software projects, we have a process for communicating major changes to GNU Radio early, using what we call GNU Radio Enhancement Proposals (GREPs). We manage GREPs in a git repository: https://github.com/gnuradio/greps The purpose of GREPs

[Discuss-gnuradio] [GREP] Remove log4cpp

2018-12-27 Thread Martin Braun

[Discuss-gnuradio] [GREP] Separate scheduler and GNU Radio base files

2018-12-27 Thread Martin Braun
Hi all, final GREP of the day: https://github.com/gnuradio/greps/blob/master/grep-0016-separate-scheduler.md This is possible the most fundamental and influential GREPs that were added so far. I would find it hard to find any reasons not to do this -- of course, the question remains, who will do

[Discuss-gnuradio] [GREP] Replace SWIG

2018-12-27 Thread Martin Braun
Hi all, https://github.com/gnuradio/greps/blob/master/grep-0015-remove-swig.md this might be the craziest GREP yet: How about we kill SWIG as a dependency? Note: We don't want to remove functionality, and we love our Python bindings. But, could we do better? SWIG slows down our compilers,
