Abstract

A method of decoding using a log posterior probability ratio L(uk), which is a function of forward variable α (.) and backward variable β (.). The method comprises dividing the forward variable α (.) and the backward variable β (.) into, for example, two segments p and q, where p plus q equal the length of the code word U. The forward segments α (.) are parallel calculated, and the backward segments β (.) are parallel calculated. The ratio L(uk) is calculated using the parallel calculated segments of α (.) and β (.).
