1. A method for estimating a performance of a wireless communication network for a given time-frequency resource allocation, wherein said communications in said wireless communication network occur on a subset of time and frequency resources defined according to a frequency hopping sequence characterized in that said communications are subject to interferences whose activation is modeled by a binary random variable bt indicating whether an interferer is active or not at a time instant t, the discrete-time stochastic process {bt}t∈[−∞;+∞] being modelled by a Markov chain with memory M on a finite space, M being a positive integer, said method comprising at least one iteration of:
Obtaining, from a receiver, at least one set of consecutive observations of interference activation {bt−M, . . . , bt};
Determining a frequency channel sequence {nƒ(t−M), . . . , nƒ(t)} associated with the at least one set of consecutive observations of interference activation {bt−M, . . . , bt} from said frequency hopping sequence, where nƒ(t) is an index of a frequency channel used for communicating at time t;
Identifying a Markov chain associated with the determined frequency channel sequence;
Updating a set of probabilities of the identified Markov chain according to the obtained at least one set of consecutive observations of interference activation.
