In　this　paper,　we　propose　an　efficient　antenna　selection　algorithm　for　wireless　MIMO　systems　with　low　computational　complexity　especially　when　calculating　the　channel　capacity.　Our　method　achieves　similar　capacity　as　that　of　the　G-circles　algorithm,　which　is　a　little　lower　than　that　of　the　optimal　antenna　selection　technique.　Simulation　results　demonstrate　that　the　proposed　antenna　selection　algorithm　achieves　high　performance　in　terms　of　bit　error　rate　(BER).
