Error in electronic communications; and problems of identity and data integrity. Several authors provide in-depth analysis of the interaction between ECC provisions and other relevant legal regimes (including the United States, ASEAN, the EU, Sri Lanka, India, and China), as well as the interrelations between the ECC and ICC rules, rules under the CISG, and the trade usages of the lex mercatoria. The various contributors highlight issues arising from each ECC provision, and provide well-informed insight into how remaining problems are likely to be resolved as the Convention enters into force. Stakeholders from all concerned sectors of the legal community businesspersons and their counsel, IGO and government officials, and academics will benefit greatly from the detailed information, analysis, and guidance offered here.
This book, edited and authored by world leading experts, gives a review of the principles, methods and techniques of important and emerging research topics and technologies in wireless communications and transmission techniques. The reader will: - Quickly grasp a new area of research - Understand the underlying principles of a topic and its application - Ascertain how a topic relates to other areas and learn of the research issues yet to be resolved - Reviews important and emerging topics of research in wireless technology in a quick tutorial format - Presents core principles in wireless transmission theory - Provides reference content on core principles, technologies, algorithms, and applications - Includes comprehensive references to journal articles and other literature on which to build further, more specific and detailed knowledge
For courses in Electronic Communications Technology (one or two-semester sequence), Microwave Communications, Wireless Communications, Communications Maintenance Technology, and Introduction to Telecommunications. Electronic Communications: A Systems Approach provides a comprehensive overview of wireless, wired, analog, and digital electronic communications technologies at the systems level. The authors' carefully crafted narrative structure helps readers put the many facts and concepts encountered in the study of communications technologies into a larger, coherent whole. Topics covered include modulation, communications circuits, transmitters and receivers, digital communications techniques (including digital modulation and demodulation), telephone and wired computer networks, wireless communications systems (both short range and wide area), transmission lines, wave propagation, antennas, waveguides and radar, and fiber-optic systems. The math analysis strikes a middle ground between the calculus-intensive communications texts intended for four-year BSEE programs and the math-avoidance path followed by some texts intended for two-year programs.
