We present an optimal fair power allocation and receiver combination scheme for multiuser indoor visible light communication systems using CDMA. MIMO diversity is achieved by using multiple LEDS and photodetectors with different orientations, resulting in a greater than 3 dB power advantage compared with MISO schemes.
This paper proposes a new two-wavelength design for large-enterprise access links. The goal of this design is to lower power consumption and equipment costs without having a significant impact on performance. In our design, one wavelength is used as part of a lower-rate static circuit for general-purpose IP traffic, while the second wavelength is dynamically configured into a high-rate circuit for...
