Data width requirements in SISO decoding with module normalization.

Data width requirements in SISO decoding with module normalization.

This letter studies the numerical properties of log-MAP-based soft-input soft-output decoding. The ranges of the differences between the path metrics, the soft output, and the complete information are derived. Since the log-MAP algorithm is functionally dependent only upon the differences between pa...
