#The Standard Library
This is the repository for the Software Defined Radio/DSP-focused version of The Standard Library, or TSL.
#Building
You will need Python installed. Invoke ./waf configure to configure the build,
and ./waf build to build the tools.
The applications will end up in build/release/bin
##Dependencies
The TSL currently depends on:
- ConcurrencyKit (https://github.com/concurrencykit/ck)
- libjansson
- librtlsdr
As well, some scripts will use GNUradio (since reimplementing Parks-McClelland would be just a waste of time!).
#Tools
There are a number of applications in this repo.
##MultiFM
MultiFM is the heart of the TSL distribution for SDR. This allows a user to take a broadband chunk of the spectrum and subdivide it into multiple arbitrarily spaced narrowband channels. MultiFM is optimized for environments with relatively limited compute resources. Almost every step of the signal processing chain is is fixed point. Some functions make use of NEON intrinsics when built for ARM.
Sample configuration files can be found in etc. This includes a sample filter
for FLEX pager channels, and sample configuration for multifm. The configurations
should be largely self-explanatory.
Invoke MultiFM with multifm [configuration file 1] ... [configuration file n].
##Resampler
Resampler is a simple rational resampler. Given an appropriate filter and set of command line filters, Resampler will allow a user to perform a rational resampling of samples from an input fifo, and write the resampled samples to the output fifo.
See resampler -h for information on the specific parameters to use.
A script, in scripts/design_interpolation_filter.py will generate a filter that
can be used with Resampler as an input. This script requires GNURadio be installed.
#License
The TSL, MultiFM and Resampler (as well as libfilter, etc.) are provided under two licenses - the GPLv2 and the MIT/X license. You can pick whichever license works best for you.
