| Abstract: | Antenna selection is an effective method to reduce the number of radio frequency chains and improve the spatial correlation properties.Among the existing algorithms,the ones based on the systemic capacity and error rate have their characters and applicable circumstances respectively.After an elaborate analysis of the two algorithms,a new antenna selection algorithm,i.e.SCE(Simultaneous Capacity and Error-rate)is proposed,and its algorithmic performance is analyzed at length through simulation. |

| Keywords: | radio communication multiple-input multiple-output(MIMO) antenna selection channel capacity error rate |
