Available in PDF, EPUB and Kindle. Book excerpt: This thesis is concerned with the efficient design of digital modulation and error-control schemes for point-to-point meteor-scatter communication systems. The methods introduced exploit the unique properties of the meteor-scatter channel. A channel model is derived based on the work of other researchers. The channel model includes expressions for meteor arrival rate, burst duration, and received power. Meteor arrivals are modeled as a Poisson random process and the properties of the Poisson process are used extensively. Channel noise is modeled as additive, white, and Gaussian distributed. The multipath structure of the channel is evaluated only to the extent that it affects channel bandwidth. New expressions for long run average bit rate and mean message waiting time. Bounds on the improvement in mean waiting time over the fixed-rate modem are derived. M-ary modulation methods are investigated to find the optimal modulation for the fixed-rate modem and adaptive-symbol-rate modem. It is shown that the adaptive-symbol-rate modem is not optimal on a bandwidth-limited channel. An alternative scheme, called adaptive quadrature amplitude modulation (QAM) is evaluated and shown to outperform adaptive-symbol-rate modulation on a bandwidth-limited channel. (rh).

Download or read book Wireless Communications written by Jack M. Holtzman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past several years have been exciting for wireless communications. The public appetite for new services and equipment continues to grow. The Second Generation systems that have absorbed our attention during recent years will soon be commercial realities. In addition to these standard systems, we see an explosion of technical alternatives for meeting the demand for wireless communications. The debates about competing solutions to the same problem are a sign of the scientific and technical immaturity of our field. Here we have an application in search of technology rather than the reverse. This is a rare event in the information business. Happily, there is a growing awareness that we can act now to prevent the technology shortage from becoming more acute at the end of this decade. By then, market size and user expectations will surpass the capabilities of today's emerging systems. Third Generation Wireless Information Networks will place even greater burdens on technology than their ancestors. To discuss these issues, Rutgers University WINLAB plays host to a series of Workshops on Third Generation Wireless Information Networks. The first one, in 1989, had the flavor of a gathering of committed enthusiasts of an interesting niche of telephony. Presentations and discussions centered on the problems of existing cellular systems and technical alternatives to alleviating them. Although the more distant future was the announced theme of the Workshop, it drew only a fraction of our attention.
