Patent
CA 2238347
Methods and system for measuring signal noise of supervisory audio tones (SATs) in radiocommunication systems are disclosed. Exemplary embodiments involve extracting a real component from a received SAT signal, removing the SAT signal portion and examining the remainder to determine a noise component present in the SAT. The noise component can be compared with a signal strength measurement to obtain a signal-to-noise ratio.
L'invention concerne des procédés et des systèmes permettant de mesurer le bruit d'un signal de tonalités audio de surveillance (SAT) dans des systèmes de radiocommunication. Les modes de réalisation illustratifs comprennent l'extraction d'une composante réelle d'un signal SAT reçu, l'élimination de la partie du signal SAT et l'examen de la partie restante afin de déterminer une composante de bruit présente dans le SAT. On peut comparer la composante de bruit à une mesure de la puissance du signal pour obtenir un rapport signal/bruit.
