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.
