forward error correction (FEC) algorithms - header files

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:

 1. 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)
 2. Reed-Solomon encoders and decoders for any user-specified code.
 3. Optimized encoder and decoder for the CCSDS-standard (255,223)
  Reed-Solomon code, with and without the CCSDS-standard "dual basis" symbol
  representation.
 4. 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.
 4. 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.
 5. 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.
