Abstract
redOptical positioning systems have raised interest in recent years, due to the centimeter accuracy in
three-dimension environments they are able to provide, thanks to the use of light emitting diodes (LED)
and diode photoreceptors. This work is based on the design and implementation of the signal processing
algorithms for an optical indoor positioning system. It is configured using some LED beacons placed at
known positions and the corresponding receivers to be positioned moving in the coverage area. The
definition and design of the hardware architecture for the processing associated to the receiver, for the
case of a Quadrant Photodiode Angular Diversity Aperture (QADA) detector is proposed, analyzing
different aspects involved in the final performance, such as the fixed-point notation used in the hardware
definition. Furthermore, the implementation of the proposal includes an analog conditioning stage, an
acquisition system, as well as a FPGA-based (Field-Programmable Gate Array) System-on-Chip (SoC) for
implementing the necessary hardware and software elements, required to estimate the final position
coordinates of the QADA receiver. In addition to the description of the positioning system and all its
stages, some preliminary experimental tests are also shown, including position estimation for two specific
locations, achieving the validation of a processing system associated with indoor positioning systems
capable of handling high data rates (in the range of Msps).
