How to correctly set PYTHONPATH for Visual Studio Code
问题 How do I correctly set up the $PYTHONPATH variable for my workspace in VisualStudio Code? Background Information I have installed two versions of GNURadio: GNURadio version 3.7.11 installed by the Linux Mint package manager in /usr/lib/python2.7/dist-packages/gnuradio GNURadio version 3.7.13.4 installed by PyBOMBS in /home/tejul/Documents/gr13/default/lib/python2.7/dist-packages/gnuradio (my prefix directory is ~/Documents/gr13/default ) I can use the newer version of GNURadio version only
gnuradio 中频信号
gnuradio中频信号 sdr设备只能输出的频率范围只能输出采样率宽度的信号。如果要采集超出这个范围的信号，就要调整中频信号。让带宽覆盖要采集的频率。 来源： https://www.cnblogs.com/xuxiao951/p/11326770.html

Using gr::fec::code::cc_encoder class in a hierarchical block
问题 I have implemented a very basic C++ CCSDS convolutional encoder (k=7,r=1/2) and it works fine. However, it is very basic and it lacks options such as operational mode (CC_STREAMING, CC_TERMINATED, CC_TAILBITING, CC_TRUNCATED) etc ..etc. Therefore, I have decided to use the default gnuradio gr::fec::code::cc_encoder class. My coding superclass will include puncturing and other blocks and therefore everything will be in a hierarchical block. So far I'm putting the blocks one by one in the
How exactly is hier_block 's behaviour different then that of a sync_block in GNU Radio?
问题 This is a continuation of this question. I understand that we cannot access input_items in __init__ of a sync_block but we can do so in hier_block (eg. here). I wanted to add a panel on the top block frame which can only be done by assigning a panel to self.win in __init__ (like in the hier_block example). If I try to assign a panel to self.win inside the work function of a sync_block then it gives the error : 'xyz' object has no attribute 'win' . Though it works if I assign a panel to self

update a variable in GNU Radio over the network
问题 I am using GNU Radio to stream RF data out using a UDP sink. The data is streamed to a controlling program. As part of this process I am frequency shifting (with a multiply block), filtering and down sampling. I would like to change the values of frequency shift at run time. Is there a way for me to have values from a UDP source saved directly to a variable? The only solution I can think of now is to forever generate a sine wave and then pipe that into GNU Radio, and then multiply my signal
