Title
(EN) PACKET ERROR RATE ESTIMATOR FOR A RADIO
(FR) ESTIMATEUR DE TAUX D'ERREUR DE PAQUET DESTINÉ À UNE RADIO
Abstract
(EN)
A packet error rate estimator is configured to estimate packet error rate (PER). In an example, power or energy is calculated in one or more streams of I/Q samples over a period of time. The power or energy may be calculated for periods of time, e.g., bit-length periods of time, and a maximum value of bit-length power or energy may be selected over a packet-length period of time. The maximum power or energy associated with each stream of I/Q samples over the period of time may be compared to at least two threshold values. Each threshold value may be associated with an expected PER. Based at least in part on the comparing, and which of a plurality of threshold values were (or were not) exceeded, a PER may be estimated for each stream of I/Q samples. The PER may be used to select a channel plan with less radio frequency noise.

L'invention concerne un estimateur de taux d'erreur de paquet qui est configuré pour estimer un taux d'erreur de paquet (PER). Selon un exemple, la puissance ou l'énergie est calculée dans un ou plusieurs flux d'échantillons I/Q sur une période de temps. La puissance ou l'énergie peut être calculée pour des périodes de temps, par exemple des périodes de temps de durée de bit, et une valeur maximale de puissance ou d'énergie de longueur de bit peut être sélectionnée sur une longueur de période de temps de paquet. La puissance ou l'énergie maximale associée à chaque flux d'échantillons I/Q sur la période de temps peut être comparée à au moins deux valeurs de seuil. Chaque valeur de seuil peut être associée à un PER attendu. Sur la base, au moins en partie, de la comparaison, et des valeurs parmi une pluralité de valeurs de seuil qui ont été (ou non) dépassées, un PER peut être estimé pour chaque flux d'échantillons I/Q. Le PER peut être utilisé pour sélectionner un plan de canal avec moins de bruit de radiofréquence.
