Coding Theory in Optical Wireless Communication Systems
This book focuses on optical-wireless communication systems. It summarizes the author's optical-wireless communication coding work while carrying out pertinent scientific research programs. The primary topics covered in the book are channel coding, coding modulation, error control (channel coding), and channel equalization. The author's mathematical analysis and experimental studies on the key theoretical issues are discussed in the book. One of the book's outstanding aspects is its thorough and methodical discussion of practical optical-wireless communication challenges. This makes the book especially appealing to readers who are eager to learn about applicable solutions in this area. Researchers, engineers, and graduate students in the subject of telecommunications can all profit from the book. It is appropriate for senior undergraduates, lecturers at colleges and universities, graduate students, and engineering and technical workers involved in optical communication.
Near-Earth Laser Communications
Invented more than a hundred years ago by Alexander Graham Bell, the technology of free-space optical communications, or lasercom, has finally reached the level of maturity required to meet a growing demand for operational multi-giga-bit-per-second data rate systems communicating to and from aircrafts and satellites. Putting the emphasis on near-earth links, including air, LEO, MEO, and GEO orbits, Near-Earth Laser Communications presents a summary of important free-space laser communication subsystem challenges and discusses potential ways to overcome them. This comprehensive reference provides up-to-date information on component and subsystem technologies, fundamental limitations, and appr...
Transmitter Power Requirements of Optical and Radio Communication Systems
The recent development of the laser has made possible communications with a beam of coherent light. Since coherent light offers great advantages over radio in the areas of beam directivity and information capacity, optical communication systems have been proposed for many uses. The first section of this thesis gives a phenomological description of laser operation. A short summary is then given of the characteristics of presently available lasers. The third section includes an extensive discussion of the requirements of optical communication systems using both laser and conventional sources. Using the information contained in the first section of the thesis, calculations are made concerning the required transmitter power to maintain communications with both radio and optical systems. Where possible, the proposed optical systems are compared with existing radio systems. It is found that, in general, the laser systems offer no significant power advantage over radio systems despite the higher directivity of the optical antennas. Consequently, the largest demand for laser communication systems will occur when it is necessary to transmit extremely large information rates.
