Sliding block traceback decoding of block codes

Sliding block traceback decoding of block codes. Block by block basis decoding is performed in which a single block, and its corresponding overlap portion, are processed during a given time. The traceback saves a record of decision (e.g., among possible trellis branches between various trellis stages) and constructs only the surviving paths through each individual block. Since only one block (by also employing its corresponding overlap portion) is decoded per time, the traceback through the coded block signal is short. One block of the coded block signal is decoded at a time, and certain resulting information (e.g., bit estimates and/or states) of a first decoded block can be leveraged when decoding a second/adjacent block.
