Visible light communications (VLC) rely on white light emitting diodes (LEDs) to transmit information and provide illumination. White LEDs act as low pass filters and thus place a limitation on achievable data rates in VLC. Orthogonal frequency division multiplexing (OFDM) has been applied to VLC to best make use of the available modulation bandwidth through bit loading. However, VLC-OFDM waveforms...
Networks of portable wireless devices have shown enormous promise in improving communications and sensing capabilities in a large number of important applications. While much work has focused on using specialized sensors to obtain information about the physical environment, we examine the problem of exploiting the received signal strength (RSS) measurements already being used for ad-hoc networking...
