METHOD AND APPARATUS FOR EFFICIENTLY CALCULATING LOG-LIKELIHOOD RATIOS

A method and an apparatus for determining the log-likelihood ratio of a received signal. The log-likelihood ratio is determined by calculating distance between the received symbol and closest constellation point matching a bit and the distance between the received symbol and the closest constellatio...

Summary:A method and an apparatus for determining the log-likelihood ratio of a received signal. The log-likelihood ratio is determined by calculating distance between the received symbol and closest constellation point matching a bit and the distance between the received symbol and the closest constellation point not matching the bit. L'invention concerne un procédé et un appareil de détermination du taux de probabilité d'un signal reçu. On détermine le taux de probabilité en calculant la distance entre le symbole reçu et le point de constellation le plus proche et correspondant un bit et la distance entre le symbole reçu et le point de constellation le plus proche ne correspondant pas au bit.
