Multiuser MISO indoor visible light communications

Visible light communications is an energy efficient and cost effective solution for indoor wireless connectivity. In this paper we explore algorithms for supporting many users concurrently by optimizing the use of individual LEDs in each luminary. The directionality of LEDs is considered when assigning multiple LEDs to a user, forming a multiple input single output (MISO) system. Exploiting the spatial separation of detectors, MISO techniques using code division multiple access and minimum mean square error detection can offer high performance to simultaneous users while preserving the properties of the lighting system, such as spatially and temporally continuous dimmable illumination.
