Embodiment Construction
[0040] The present invention is described in further detail below in conjunction with accompanying drawing:
[0041] see figure 1 , 2 , 3, 4, the MIMO antenna selection module disclosed in the present invention adopts the random approximation optimization algorithm of the sequential mode to quickly optimize the selection of the transceiver antenna sub-array of the 60GHz large-scale antenna array system, thereby effectively reducing the complexity of system implementation and cost. In order to maximize the beamforming gain of the MIMO system, the optimization objective function involved in the method is defined as the main singular value of the sub-channel matrix corresponding to the antenna array. The objective function of antenna selection involved is not derived from the results of channel estimation, but by using the characteristic of the 60GHz channel having a strong line-of-sight component, and estimating the right boundary of the Gael disk of the channel matrix through...
