    说明:  基于Matlab的MIMO通信系统仿真”,收获良多,特将其记录下来,与诸位分享。此主题分为上下两部分,第一部分主要涉及系统架构,第二部分侧重程序优化。若能帮助读者一二,实属万幸。(Multi-input multi-output (MIMO) communication system based on Matlab simulation ", so, will its record, share with you. This topic is divided into two parts, the first part mainly involves the system architecture, the second part focuses on process optimization. If can help readers just a little, is lucky.)

    The first scheme is based on the spatial locality of feature vectors corresponding to similar images. Learning is effected by modifying the query vector to incorporate the positive examples. The second scheme is based on “distorting” our view of the feature space. An new similarity distance between an image and the query is learned from the relevance feedback.
