Topics include historical perspective, channel impairments, amplitude constraints and the characteristics of popular optoelectronic components. A variety of wireless optical channel topologies are presented along with a survey and analysis of present day signalling techniques employed for these channels. The author provides a unifying framework for signalling design which allows the channel constraints to be represented geometrically and permits the use of modem design principles from electrical channels. Modulation schemes are designed using the formalism of lattice codes and a design process for signalling sets is specified. The use of multiple-input/multiple-output (MIMO) wireless optical channels to improve the spectral efficiency of links is explored. The basic spatio-temporal modem design problem is specified and a spatial multiplexing gain is quantified. New spatial discrete multitone modulation is proposed and the unique features are discussed. Based on measurements on an experimental prototype, a channel model is formulated and a realizable spatio-temporal coding scheme is simulated to quantify performance gains. This volume is organized for professional and academic readers engaged in modem design for wireless optical intensity channels. Significant background material is presented on both the properties as well as on fundamental communications principles. Wireless Optical Communication Systems can be used by physicists and experimentalists as an introduction to signalling design as well as communication systems designers. 0aENGINEERING. 0aCOMPUTER COMMUNICATION NETWORKS. 0aMICROWAVES. 0aTELECOMMUNICATION.14aENGINEERING.24aCOMMUNICATIONS ENGINEERING, NETWORKS.24aCOMPUTER COMMUNICATION NETWORKS.24aMICROWAVES, RF AND OPTICAL ENGINEERING.2 aSpringerLink (Online service)0 tSpringer eBooks08iPrinted edition:z978038722784940uhttp://dx.doi.org/10.1007/b99592zVer el texto completo en las instalaciones del CICY  2ddccER  c32042d32042  00102ddc40708LEaCICYbCICYcELd2025-07-10l0o621.382r2025-07-10 08:39:26w2025-07-10yER
