Title
(EN) STOCHASTIC LINEAR DETECTION
(FR) DÉTECTION LINÉAIRE STOCHASTIQUE
Abstract
(EN)
Apparatuses, systems, and methods are disclosed for stochastic linear detection. A digital signal processor (150) determines information about a plurality of transmitted signals based on a plurality of received signals. An initialization module (402) determines an estimator matrix and a noise shaping matrix based on channel state information that relates the transmitted signals to the received signals. A sample generation module (404) stochastically generates a plurality of signal estimates so that each signal estimate is a sum of a fixed component and a random component. The fixed component may be based on applying the estimator matrix to a vector of the received signals, and the random component may be based on applying the noise shaping matrix to generated noise. An output module (406) sends soft information based on the plurality of signal estimates to an error-correcting code (ECC) decoder (208), for decoding bits carried by the transmitted signals.

L'invention concerne des appareils, des systèmes et des procédés pour une détection linéaire stochastique. Un processeur de signaux numériques (150) détermine les informations concernant une pluralité de signaux transmis sur la base d'une pluralité de signaux reçus. Un module d'initialisation (402) détermine une matrice d'estimation et une matrice de mise en forme de bruit sur la base d'informations d'état de canal ui mettent en relation les signaux transmis et les signaux reçus. Un module de génération d'échantillon (404) génère de manière stochastique une pluralité d'estimations de signal de telle sorte que chaque estimation de signal est une somme d'un composant fixe et d'un composant aléatoire. Le composant fixe peut être basé sur l'application de la matrice d'estimation à un vecteur des signaux reçus, et le composant aléatoire peut être basé sur l'application de la matrice de mise en forme de bruit à un bruit généré. Un module de sortie (406) envoie des informations souples sur la base de la pluralité d'estimations de signal à un décodeur (208) de code de correction d'erreur (ECC), pour décoder des bits portés par les signaux transmis.
