Embodiments of the present disclosure provide a MIMO communication method and system, and a receiver node. The method includes: receiving, by a number of optical detection modules of a receiver node, optical signals transmitted by a number of optical transmission modules of a transmitter node. Different optical detection modules of the receiver node have different orientations, and different optical transmission modules of the transmitter node have different orientations.

MIMO transmission method and system, and receiver node

A method for controlling a transmit power of a terminal, and a terminal, where the method and the terminal include, working states of a first antenna and a second antenna may be monitored, and then a transmit power of the first antenna or that of the second antenna may be controlled according to a preset correspondence. Therefore, according to the method and the terminal, a transmit power of an antenna in a working state in the first antenna and the second antenna may be accurately controlled. If the transmit power is less than a standard transmit power, a Specific Absorption Rate (SAR) can be reduced.

A method and device for extracting color features, relating to the field of image processing includes converting an original image into sub-images corresponding to channels in a color space, dividing the sub-images into a plurality of cells with identical size, and calculating the color histograms of each of the plurality of cells. A cell and neighboring cells thereof are defined as the effective scope of the cell, and a feature vector of the cell is determined according to a degree of similarity of the color histograms of every two neighboring cells in the effective scope. The feature vectors of the cells in the sub-images are concatenated to obtain feature vectors of the sub-images, and a feature vector of the original image is obtained according to the feature vectors of the sub-images.
