Re: Question viterbi decoder

SIMD Viterbi Decoder provides library functions to decode certain popular error correction codes.

version supports two codes: a rate 1/2, constraint length 7 (r=1/2, k=7) code, and an r=1/2, k=9 code. Four implementations of each decoder are provided.
One is in portable C and should run in any GNU C environment.

The other three use the IA32 SIMD (single instruction, multiple data) instruction sets: MMX, SSE, and SSE2. The SSE version of the k=7 decoder executes at ~9 megabits/sec on a 1GHz Pentium-III.

I shall upload some source for this viterbi decoder.
