FOR 197
.~.~ Trellis code (371/43.4)
DEFINITION
Classification: 714/FOR.197
Trellis code:
Foreign art collections including subject matter where, for a convolutional code of k bits length, an inverse coding operation is performed in which 2k-1 decision bits are used to select an output bit and where after many branches, the most probable path will be selected with a high degree of certainty, and where the branches form a mesh pattern (i.e.., branches start at a plurality of points and intersect other branches).
