At present, the communication systems in Aircrafts involve messy wiring. Such wiring systems require more time for construction and leads to considerable time delay in faulty location. In addition to the cost of lengthy wires, many accidents have been reported due to faulty wiring in aircrafts. To overcome these difficulties, researches are carried out all over the world to develop an efficient wireless communication system. In this book, it is proposed to develop a design procedure for wireless communication system for aircrafts using space division multiple access. Noise from external sources interfere the signals transmitted and the quality of the communication gets degraded. The major aim of this book is to identify and eliminate the additive white Gaussian noise in the communication channel and thereby enhance the quality of wireless communications in the Aircraft.
