This　paper　provides　the　robust　filtering.　problem　for　linear　uncertain　discrete　time-delay　systems　with　Markovian　jump　parameters.　The　system　under　consideration　is　subjected　to　time-varying　norm-bounded　parameter　uncertainties.　The　sufficient　condition　for　the　existence　of　solutions　to　the　problem　is　presented　in　terms　of　a　set　of　coupled　linear　matrix　inequalities　(LMIs),　which　guarantees　that　the　augmented　system　is　robustly　stochastically　stable　in　the　mean　square,　irrespective　of　the　admissible　uncertainties　as　well　as　the　time-delay.　A　numerical　example　is　provided　to　illustrate　the　proposed　design　approach.
