About the Authors

Balancing theoretical analysis and practical advice, this book describes all the underlying principles required to build high performance indoor optical wireless communication (OWC) systems based on visible and infrared light, alongside essential techniques for optimising systems by maximising throughput, reducing hardware complexity and measuring performance effectively. It provides a comprehensive analysis of information rate-, spectral- and power-efficiencies for single and multi-carrier transmission schemes, and a novel analysis of non-linear signal distortion, enabling the use of off-the-shelf LED technology. Other topics covered include cellular network throughput and coverage, static resource partitioning and dynamic interference-aware scheduling, realistic light propagation modelling, OFDM, optical MIMO transmission and nonlinearity modelling. Covering practical techniques for building indoor optical wireless cellular networks supporting multiple users and guidelines for 5G cellular system studies, in addition to physical layer issues, this is an indispensable resource for academic researchers, professional engineers and graduate students working in optical communications.
- Demonstrates the key principles that enable LEDs to transmit wireless data at very high speeds, and delivers design guidelines for building and optimising such OWC systems
- Delivers a framework for optimising multi-carrier signals, taking into consideration the properties of practical off-the-shelf front-end components which maximises the throughput of OWC links
- Explains realistic and comprehensive channel modelling in a cellular OWC network in an aircraft cabin via Monte Carlo ray-tracing, providing a realistic assessment of system performance in a practical multi-user communication set-up
- Evaluates the analysis and performance of a novel low-complexity MIMO transmission scheme, spatial modulation, which reduces hardware complexity and improves transmission rates
