METHOD AND DEVICE FOR CALCULATING STATISTICAL PARAMETERS OF THE PROPAGATION CHANNEL

摘要

Method for calculating in real or quasi-real time, the values of the statistics of a propagation channel in order to allocate resources to one or more communication links in a communication network comprising at least the following steps: Estimate in real time or quasi-real the statistical parameters Kl and Gl of the propagation channel for each link l of the network using the information coming from training sequences contained in the received signal, (61), From the estimations of the stored propagation channel, at a receiver, execute the following steps in parallel: - detect if there is a change in the statistical distribution of the stored samples indicating a break, (62), If a break is detected, keep some of the samples from estimate the channel statistic, (63), and estimate the Kl statistic, using part of the samples, Otherwise, when no break is detected ect estimate the Kl statistic of the channel on the last samples, (64), - estimate the Gl statistic of the channel using a sliding time window, (66), Transmit (65) the values of the calculated channel statistics to a allocator of resources which takes into account the service constraints and defines the allocation of resources according to the estimates of the channel statistics.
