Abstract
(EN)
Some embodiments of a method may include: receiving a signal and performing analog RF combining; down-converting the combined received signal; providing the down-converted combined signal to an artificial neural network (ANN); using predetermined weights to obtain log likelihood ratios (LLRs) in the absence of channel state information; and processing the LLRs with a channel decoder to obtain uncoded bits.
(FR)
Certains modes de réalisation d'un procédé peuvent comprendre : la réception d'un signal et la réalisation d'une combinaison RF analogique; la conversion descendante du signal reçu combiné; la fourniture du signal combiné converti vers le bas à un réseau neuronal artificiel (ANN); l'utilisation de facteurs de pondération prédéterminés pour obtenir des rapports de probabilité logarithmique (LLR) en l'absence d'informations d'état de canal; et le traitement des LLR avec un décodeur de canal pour obtenir des bits non codés.
