Diseño de un transceptor síncrono de espectro ensanchado por salto rápido en frecuencia para comunicaciones ópticas no guiadas en interiores

Abstract

In this paper, the design and experimental characterization of a Wireless Optical Fast Frequency Hopping Spread Spectrum (FFHSS) transceiver is presented. It has been designed for indoor applications and supposing a master transmitter emitting a pilot signal to synchronize all the receivers. The FHSS techniques are chosen due to their robustness against narrowband interferences and multipath propagation and because they allow to use Code Division Multiple Access (CDMA). The principal objective of this work is to study a full synchronous system in which each receiver is synchronized by a reference signal emitted by a central station.
