This　paper　propose　a　novel　multi-channel　speech　enhancement　method　by　combining　the　wiener　filtering　and　subspace　filtering　with　a　convex　combinational　coefficient..　Because　of　using　both　the　advantage　in　noise　reduction　of　the　subspace　speech　enhancement　technology　and　the　stable　characteristic　of　the　Wiener　filtering　technology,　the　proposed　multi-channel　speech　enhancement　method　has　a　better　performance　in　robustly　removing　colored　noise　from　noisy　speech　signals.　Simulation　examples　confirm　that　under　different　colored　noise,　the　proposed　multi-channel　speech　enhancement　method　can　obtain　better　speech　recovery　results　than　the　traditional　subspace　multi-channel　speech　enhancement　method　and　the　multi-channel　Wiener　filter　speech　enhancement　method.
