Abstract

A multiple-input and multiple-output visible light transmitting device and method and receiving device and method. The transmitting device comprises: a signal transmitting unit and a signal modulation unit. The signal transmitting unit comprises an array consisting of 1 or more light-emitting components, where the light-emitting components are for use in emitting visible lights, and the visible lights emitted by different light-emitting components are of different frequencies. The signal modulation unit is configured as: to load a signal of each channel onto the visible light of one frequency, where the signals loaded onto the visible lights of different frequencies belong to different channels. The receiving device comprises: a signal receiving unit and a signal processing unit. The signal receiving unit comprises along an incident light direction: an incident light collimating device, a layer of substrate, and a detection array chip. A light-blocking layer is attached onto a surface of the substrate that is perpendicular to an incident light. A diffraction hole two-dimensional array constituted by 2 or more diffraction holes having different aperture sizes is arranged on the light-blocking layer. The detection array chip comprises 2 or more detection pixel elements.

Description

technical field [0001] The present invention relates to a multiple-input multiple-output (Multiple-Input Multiple-Output, MIMO for short) visible light communication system, in particular to a multiple-input multiple-output visible light transmitting device and method, and a receiving device and method. Background technique [0002] Visible Light Communications (VLC for short) is a wireless communication technology that uses visible light with a frequency between 390THz (wavelength of 770nm) and 857THz (wavelength of 350nm) as a communication medium to complete information transmission. [0003] In recent years, with the rapid development of semiconductor technology, visible light communication based on LED (Light Emitting Diode, light emitting diode) lighting has been greatly developed as a wireless access technology. Using LED visible light signal to transmit data has the following advantages: LED light source has the characteristics of low power consumption, long service ...
