DEFINITION

Classification: 714/FOR.201

Branch metric calculation:

Foreign art collections including subject matter where a tree of possible data sequences is constructed identifying the possible data sequences in terms of data states, and from which correlations are computed for selecting the paths which are to survive to the next stage of decoding received data.
