Method for computing in real or quasi-real time, values of the statistics of a propagation channel so as to allocate resources to one or more communication links between two nodes in a communication network comprising at least the following steps: estimate in real or quasi-real time the statistical parameter K l which corresponds to the ratio between the power of the signal received in direct line of sight and the power of the diffuse paths and G l corresponding to the mean gain-to-noise ratio of a Rice channel model modelled for each link l of the network by using information originating from training sequences contained in a received signal which make it possible to estimate the propagation channel,, on the basis of the propagation channel estimations stored, at a receiver, execute the following steps in parallel: - detect whether there is a change in the statistical distribution of the estimations of the channel manifesting a break,, if a break is detected, preserve part of the estimations of the channel and estimate the statistic K l, by using part T W / 2 of the estimations of the propagation channel with T W the number of estimations of the channel used to perform the break detection, otherwise, when no break is detected, estimate the statistic K l of the channel over the last T W estimations of the channel,, - estimate the statistic G l of the channel by using a sliding time window,, transmit the values of channel statistics computed to a step of allocating the resources which takes into account service constraints and defines the allocation of the resources as a function of the estimations of the statistics of the channel. estimate in real or quasi-real time the statistical parameter K l which corresponds to the ratio between the power of the signal received in direct line of sight and the power of the diffuse paths and G l corresponding to the mean gain-to-noise ratio of a Rice channel model modelled for each link l of the network by using information originating from training sequences contained in a received signal which make it possible to estimate the propagation channel,, on the basis of the propagation channel estimations stored, at a receiver, execute the following steps in parallel: - detect whether there is a change in the statistical distribution of the estimations of the channel manifesting a break,, - detect whether there is a change in the statistical distribution of the estimations of the channel manifesting a break,, if a break is detected, preserve part of the estimations of the channel and estimate the statistic K l, by using part T W / 2 of the estimations of the propagation channel with T W the number of estimations of the channel used to perform the break detection, otherwise, when no break is detected, estimate the statistic K l of the channel over the last T W estimations of the channel,, - estimate the statistic G l of the channel by using a sliding time window,, - estimate the statistic G l of the channel by using a sliding time window,, transmit the values of channel statistics computed to a step of allocating the resources which takes into account service constraints and defines the allocation of the resources as a function of the estimations of the statistics of the channel.
