Abstract
A method for determining noise associated with a received signal in a telecommunications network, the received signal being sampled beforehand in the form of a succession of data. The method includes: selecting a portion of the data in the received signal and determining a given number of possible partitions of the selected portion of the data in the received signal, the number of partitions being greater than or equal to two; partitioning all of the data in the received signal into the number of partitions; estimating mean energies of the signal in each of the partitions and identifying a partition from among the partitions having a minimum mean, the identified partition being a noise partition; and estimating a variance of the noise partition, the noise associated with the received signal being a function of the variance of the noise partition.
