Protect your bits: Introduction to gr-fec

A look into the error-correction capabilities of GNU Radio

In the 1940s, Shannon proved that we can transmit data error-free depending on rate and SNR. In practical radios, we need to employ forward error correction (FEC) to achieve those rates. GNU Radio has a built-in component to handle FEC, called gr-fec. After some basics of FEC, we will see how GNU Radio does this, and how it can be extended.
