An underwater communication system, wherein the underwater communication system is capable of increasing a data transmission through a visible light between a surface and underwater of a swimming pool and an underwater communication method providing the data transmission between the surface and the underwater of the swimming pool are provided.

Optical data transmission system for swimmers

There is provided herein a visible light-based speed estimation method ViLDAR. By using the received light intensity of a vehicle's LED headlight, the vehicle speed can be accurately estimated for a wide range of incidence angle. Linear LS method is used in one embodiment of a speed estimation algorithm. The impact of system parameters on speed estimation error and the performance of algorithm for different speed and estimation duration are provided. Some embodiments operate best at a certain distances where the received light intensity (power) reading can provide estimation results with high accuracy, which distances are termed a reliable region of operation. In addition to speed estimation, potential applications of ViLDAR idea are ranging detection and collision avoidance for autonomous vehicles.

System and method for speed estimation, detection and ranging using visible light in vehicles

A system and method are provided for communication between vehicles within a platoon of vehicles. In one embodiment, each vehicle is equipped with forward and backward directed optical emitters and receivers in operable communication with a controller. In an initialization phase, each vehicle determines its position within the platoon and the identification of all vehicles of the platoon. In a data transmission phase, each vehicle takes part in a token-based data transmission.

Communication between vehicles of a platoon

Systems and methods for adaptive multiple input multiple output (MIMO) optical orthogonal frequency division multiplexing (O-OFDM) visible light communication (VLC) involving adaptively choosing modulation type, modulation order, MIMO configuration, and MIMO type. A receiver estimates channel information, and based on the channel information, an adaptive controller makes a selection of transmission mode and provides feedback to a transmitter, which uses a set of transmission parameters indicated in the transmission mode feedback. MIMO O-OFDM VLC provides diversity gain (i.e., higher link reliability or better coverage range) and/or multiplexing gain (i.e., higher data rate).
