Specifically, an interleaved subcarrier multiplexing approach is proposed to mitigate user pair unfairness caused by the low-pass frequency response of bandlimited VLC systems, and a two-dimension (2D) power allocation strategy is further proposed to ensure both the fairness of users within each user...
For VLC, user’s orientation has to be considered; if the wave-front is parallel to an interface, signal power is at maximum, otherwise if the user’s equipment is beyond the line of sight of the LED transmitters, no signal will be received. Because of light’s physical property, user ...
The SINR for each user must be above a certain margin to provide a stable connection. RF devices use omnidirectional antennas and the signal is dependent on distance and obstacles. For VLC, user’s orientation has to be considered; if the wave-front is parallel to an interface, signal power...
VIII.Topology: it can be seen that some networks in this section are VLC but not LiFi. The reason for choosing these studies is that the methods and/or scenarios in these studies including the concepts were very similar to those in LiFi in terms of APS and HO. IX. Handover overhead: ...
