1. IntroductionΒΆ
AFF3CT is a toolbox dedicated to the Forward Error Correction (FEC or channel coding). It is written in C++ and it supports a large range of codes: from the well-spread Turbo codes to the new Polar codes including the Low-Density Parity-Check (LDPC) codes. AFF3CT includes many tools but the most important ones are:

The simulator targets high speed simulations and extensively uses parallel techniques like SIMD, multi-threading and multi-nodes programming models. Below, a list of the features that motivated the creation of the simulator:
- reproduce state-of-the-art decoding performances,
- explore various channel code configurations, find new trade-offs,
- prototype hardware implementation (fixed-point receivers, hardware in the loop tools),
- reuse tried and tested modules and add yours,
- alternative to MATLAB, if you seek to reduce simulations time.
AFF3CT was first intended to be a simulator but as it developed, the need to reuse sub-parts of the code intensified: the library was born. Below is a list of possible applications for the library:
- build custom communication chains that are not possible with the simulator,
- facilitate hardware prototyping,
- enable various modules to be used in SDR contexts.
