METHOD AND DEVICE FOR COMPUTING PROPAGATION CHANNEL STATISTICAL PARAMETERS

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 and 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 propagation channel stored, at the level of a receiver, execute the following steps in parallel: - detect if there is a change in the statistical distribution of the stored channel estimates reflecting a break, (62), If a break is detected, keep some of the channel estimates from estimate of the channel statistic, (63), and estimate the statistic, using part of the channel estimate, Otherwise, when no break is t detected estimate the channel statistic on the latest channel estimates, (64), - estimate the channel statistic using a sliding time window, (66), Transmit (65) the calculated channel statistic values to an allocator of resources which takes into account the service constraints and defines the allocation of resources according to the estimates of the channel statistics.
