The　coordination　beamforming　scheme　with　transceiver　radio　frequency　impairments　was　proposed　to　improve　the　performance　of　ultra-dense　wireless　network　(UDN).　Firstly,　the　coordination　beamforming　model　based　on　the　residual　radio　frequency　impairments　is　presented,　and　the　convex　optimization　algorithm　is　utilized　to　achieve　the　optimal　solution.　Then,　considering　the　limitations　of　the　implementation　of　the　optimal　beamformer,　the　signal　leakage　noise　ratio　based　the　linear　suboptimal　beamformer　is　designed　by　beamforming　steering　vector　and　optimal　power　allocation.　Simulations　show　that　the　proposed　suboptimal　beamformer　with　radio　frequency　impairments　can　effectively　reduce　interference　and　improve　the　sum　rate　of　UDN.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Posts　and　Telecommunications.　All　right　reserved.
