摘要： The combination of Visible Light Communication (VLC) and Multiple-Input Multiple-Output (MIMO) is used for high-data-rate indoor wireless communications. Because the traditional RF communication systems are not capable of satisfying the growing wireless communication systems. The dual function of light-emitting diodes (LEDs), such as illumination and communication to evaluate while implementing MIMO-VLC system. The LED-based VLC system has several advantages such as security, cost-effectiveness and lack of interference. In this work, the VLC system is used in an indoor environment. The LED lamps are placed at the ceiling to provide ambient light which offers rich spatial resources for VLC. Here, various LEDs such as phosphor-converted led, organic led, micro led, RGB led and white led are used and the performance of LEDs are analyzed. The type of receiver used in the MIMO VLC system is Avalanche Photodiode Detector (APD). The performance of LED is analyzed by luminous flux, luminous efficacy, switching time, data rate and brightness.
