Description of some GNU Radio blocks You can find more about the data types available in GNU Radio in the Doxygen documentation. This scheduler allows each block in a flowgraph to run in an independent thread, synchronizing only around the input and output buffers with adjacent-block threads. For creating SDR it provides less cost RF hardware and it also provides stimulation like user interface which does not required physical hardware. Installation of GNU Radio:. block diagram for library management system. It can process I/Q data from many types of input devices, including Funcube Dongle Pro/Pro+, rtl-sdr, HackRF, and Universal Software Radio Peripheral (USRP) devices. When we write the block, we need to construct them as shared libraries that may be dynamically loaded into Python using the `import' mechanism. So I opened it and looked for a work or general_work method right away (for difference between these, refer to the Guided Tutorials part 4) The ( general_ ) work method is the central workhorse of a GNU Radio block: GNU Radio's scheduler will call it whenever there are input items to process (given that there's enough output buffer space). flow_graph class.
