METHOD AND SYSTEM FOR GENERATING STATIONARY AND NON-STATIONARY CHANNEL REALIZATIONS WITH ARBITRARY LENGTH.
Currently the channel emulation is carried out by means of stationary channel realizations in order to perform the tests and validation of the new data communication schemes. However, the channel models available in the state of the art have only been efficiently used to perform channel simulation using software, leaving its efficient implementation in Hardware still unsolved. The present development details a method and apparatus for performing the channel emulation of time selective scenarios with arbitrary dispersion (channels with both isotropic and non-isotropic arrival angle distributions or channels with asymmetric and non-asymmetric power spectral densities). Likewise, the present development allows generating arbitrarily long channel realizations for channels whose statistics are non-stationary, allowing to emulate real channels. The simulation of stationary and non-stationary channels is performed by concatenating independent sequences and by applying a window to the generated sequences, through a shaping filter that allows this type of model to be implemented in selective time channel emulators in hardware. The sequences are channel realizations that are obtained from any method of generating stochastic processes such as: Sum of orthogonal functions, sum of sinusoids/cisoids, filtering, Fourier transform, etc.

Systems and methods for identifying a source of radio frequency interference in a wireless network
An interference detection system in a network identifies a first wireless station that has experienced radio frequency (RF) interference from an unknown source and identifies one or more second wireless stations that have experienced similar interference. A plurality of estimated interference source locations are scored based on a comparison of estimated interference to observed interference at the one or more second wireless stations. A predicted interference source location is identified based on the scored plurality of estimated interference source locations. It is determined whether the unknown interference source is a persistent interference source over a selected time period, wherein the predicted interference source location is identified for each interval in the selected time period. The predicted interference source locations for each interval in the selected time period are retrieved and an aggregated predicted interference source location is calculated based on the retrieved predicted interference source locations.
