The communication systems in aircrafts involve complicated wiring and increase the weight of aircrafts. Such wiring systems require more time for construction and lead to considerable time delay in fault location. When wiring problem occur, it is difficult to manage wired data transmission. In addition to the complexity of wires, many accidents have been reported due to faulty wiring in aircraft. To overcome these difficulties, researches are being carried out all over the world to develop an efficient wireless communication system. In this investigation, it is proposed to develop a design procedure for wireless communication system for aircrafts using space division multiple access technique. Noises from external sources interfere with the signals transmitted and the quality of the communication gets degraded. One of the aims of this research is to identify and eliminate the additive white Gaussian noise in the communication channel. Second aim is to establish interference free simultaneous transmission of multiple signals from different sources to the corresponding destinations. Third aim is to ensure that the signals do not get jammed and do not interfere with other onboard wireless systems. Thereby enhance the quality of wireless communication in the aircrafts. Aircraft wireless system design and indoor wireless network replace the existing indoor wired sensor network and reduce electrical wiring issues.In the proposed wireless system, radio signals from multiple wireless sensors using the space division multiple access technique increases the strength of transmission power and reduces electromagnetic signal interference. A new technique for identification and efficient transmission of signals from source to destination has been developed. The performance of proposed aircraft wireless communication model is investigated and validated for safe indoor propagation. This model enhances the overall capacity of the wireless communication system in the aircrafts.To improve the performance of the wireless communication the author has developed a new technology called avionics local area network protocol. This protocol increases strength of the signals before transmission to the receivers. Avionics local area network protocol offers solutions to interference between multiple wireless sensor signals, jamming of signals and interference with unintended signals. It also reduces wireless system issues and helps to manage the system efficiently. Simulation results of the aviolan protocol system confirm that the spectral efficiency of aircraft system is increased by improving the gain of the system. Secured wireless transmission techniques are needed to reduce indoor wiring failures in aircrafts. Efficient indoor propagation channel and high spectral efficiency are achieved for indoor wireless communication in the aircrafts by using avionics local area network protocol.

This book discusses the fundamental aspects of multiple-source Optical Wireless Applications, including Visible Light Communications (VLC). Moreover, the authors explore VLC performance in several conventional household layouts and investigate the impact of these layouts on VLC. Multiple sources increase multipath distortion. Multi-input- Multi-Output (MIMO) techniques will be included as they provide either reliability improvement or bandwidth efficiency increase. Based on these topics, the book further explores VLC performance in real applications, such as aircraft cabin wireless communications. In addition, the authors describe the Lambertian emitting pattern of LEDs and the diffused features in indoor environments. Based on the theory, they trace light pulses to establish a MIMO indoor wireless channel model on specific sources layout. Next, they generate test data to simulate BER distribution in a room and calculate the outage. Furthermore, addresses the performance improvement when MIMO techniques are applied. Lastly, the authors investigate VLC performance in specific applications, including for aircraft on-board wireless communications. Finally, the pitfalls of MIMO systems are discussed.
