gnuradio

GNU Radio Software Radio Toolkit

Variants:
GNU Radio provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic and commercial environments to support both wireless communications research and real-world radio systems.

GNU Radio applications are primarily written using the Python programming language, while the supplied performance-critical signal processing path is implemented in C++ using processor floating-point extensions, where available. Thus, the developer is able to implement real-time, high-throughput radio systems in a simple-to-use, rapid-application-development environment.

While not primarily a simulation tool, GNU Radio does support development of signal processing algorithms using pre-recorded or generated data, avoiding the need for actual RF hardware.

This package contains the gnuradio-companion, a graphical tool for creating signal flow graphs and generating flow-graph source code. Also included are a variety of tools and utility programs.

/usr/share/gnuradio/examples/atsc/README

Decoding ATSC using 19.2MSps rate over 5 processes
--------------------------------------------------

1) Verify signal, adjust antenna and find best gain setting using uhd_fft.py,
station frequency from the fcc video database, and sample rate to 6.4e6.

2) Capture data - adjust gain (-g) frequency (-f) and which side
the tvrx is on to fit your local setup:

uhd_rx_cfile.py -s --samp-rate=6.4e6 -g

These are examples of using gr-trellis in grc.

INTERFERENCE CANCELLATION
-------------------------
Two users are transmitting simultaneously using convolutionally encoded QPSK, each with power P1=alpha*P and P2=(1-alpha)*P.
The combined signal is observed in noise and four different receivers are considered:
1) A viterbi decoder decoding user 1 assuming user 2 is noise
2) A viterbi decoder decodi
