Title: Map decoder
Inventor: KATO KOJI
IPC: H04L1/00
Filed: 2001-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a MAP decoder that reduces a time required for MAP decoding and decreases the storage capacity storing the result of arithmetic operation. SOLUTION: A trellis is applied to input data from its head to its end to make an arithmetic operation α for the forward probability and applied to the input data from its end toward its head to make an arithmetic operation β for the backward probability. When the arithmetic operation for the forward probability α and the arithmetic operation for the backward probability β are conducted up to the middle of the trellis, the arithmetic result of the backward probability β is read from a memory and a combined probability λ is calculated by the arithmetic result of the backward probability β and the arithmetic result of the forward probability α.  In this case, the arithmetic result of the backward probability β is stored in a storage address of the arithmetic result of the backward probability that is read for the arithmetic operation of the combined probability λ. When the arithmetic operation of the forward probability α and the arithmetic operation of the combined probability λ are conducted up to the end of the trellis, the arithmetic operation of the forward probability αis conducted from the head of the trellis to the middle of the trellis and the combined probability λ is calculated.
