How To Install libfec-dev on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libfec-dev
on Ubuntu 20.04.
What is libfec-dev
libfec-dev is:
This package provides a set of functions that implement several popular forward error correction (FEC) algorithms and several low-level routines useful in modems implemented with digital signal processing (DSP).
The following routines are provided:
- Viterbi decoders for the following convolutional codes: r=1/2 k=7 (“Voyager” code, now a widely used industry standard) r=1/2 k=9 (Used on the IS-95 CDMA forward link) r=1/6 k=15 (“Cassini” code, used by several NASA/JPL deep space missions)
- Reed-Solomon encoders and decoders for any user-specified code.
- Optimized encoder and decoder for the CCSDS-standard (255,223) Reed-Solomon code, with and without the CCSDS-standard “dual basis” symbol representation.
- Compute dot product between a 16-bit buffer and a set of 16-bit coefficients. This is the basic DSP primitive for digital filtering and correlation.
- Compute sum of squares of a buffer of 16-bit signed integers. This is useful in DSP for finding the total energy in a signal.
- Find peak value in a buffer of 16-bit signed integers, useful for scaling a signal to prevent overflow.
This package automatically makes use of various SIMD (Single Instruction stream, Multiple Data stream) instruction sets, when available: MMX, SSE and SSE2 on the IA-32 (Intel) architecture, and Altivec on the PowerPC G4 and G5 used by Power Macintoshes.
