A go-back-N protocol for Mobile Communications
IEEE Transactions on Vehicular Technology, 1991Co-Authors: Giuliano BenelliAbstract:The author describes a go-back-N (GBN) protocol, which is a type of automatic repeat request (ARQ) technique. The protocol has a buffer and memory at the receiver side and offers low implementation complexity and a structure especially suited to Mobile Communications. The optimization of the protocol parameters is determined through numerical analysis. Performance is evaluated by computer simulation using a channel model suitable for Mobile Communications. The results show that the proposed ARQ scheme achieves a higher performance than that of other ARQ protocols and that at high error rates its efficiency compares favorably with selective repeat protocols having an infinite buffer. >

Expanded Satellite-based Mobile Communications Tracking System
2007Co-Authors: Amy Houser, Derrick Vercoe, Peggy Erlandson, David F Williams, Mala Raman, Jennifer WittpennAbstract:This U.S. Department of Transportation (USDOT) Federal Motor Carrier Safety Administration (FMCSA) project was authorized in the 2004 Senate Conference Report 108-401: As proposed by the Senate, the conference agreement directs $2,000,000 from funds provided for the high-priority initiative program for an expanded satellite-based Mobile Communications system to monitor and track hazardous materials and high-value cargo in uncovered areas of the United States. As a result, a regional assessment and 3-month pilot test was conducted to test a wireless, satellite-based Mobile Communications tracking system to monitor hazardous materials and high-value cargo in order to improve Communications in certain regions of Alaska and Hawaii, where satellite-based tracking services were only partially available. This document represents the Final Report for this pilot test of an Expanded Satellite-based Mobile Communications Tracking System.

A perspective on the evolution of Mobile Communications
IEEE Communications Magazine, 2003Co-Authors: K. TachikawaAbstract:This article outlines the current state of Mobile Communications and presents some of the future directions in research and development from the perspective of NTT DoCoMo with special emphasis on the market in Japan. It first describes the directions in which Mobile Communications are expected to forge ahead in the future, and the service implementation strategies they could employ. Then it describes an example of Mobile multimedia services and present an outline of the Freedom of Mobile Multimedia Access (FOMA), which is a service based on the 3G Mobile Communications system called International Mobile TeleCommunications-2000 (IMT2000). This is followed by an overview of our R&D approach to 4G systems, which constitute Mobile Communications systems of the future, and the profile of technologies to make these happen. Finally, it reviews our approach to future technologies that are expected to be realized in 4G and subsequent systems, and illustrate it with an example of a research project.

applications of antenna arrays to Mobile Communications i performance improvement feasibility and system considerations
Proceedings of the IEEE, 1997Co-Authors: L C GodaraAbstract:The demand for wireless Mobile Communications services is growing at an explosive rate, with the anticipation that communication to a Mobile device anywhere on the globe at all times will be available in the near future. An array of antennas mounted on vehicles, ships, aircraft, satellites, and base stations is expected to play an important role in fulfilling the increased demand of channel requirement for these services, as well as for the realization of the dream that a portable Communications device the size of a wristwatch be available at an affordable cost for such services. This paper is the first of a two-part study. It provides a comprehensive treatment, at a level appropriate to nonspecialists, of the use of an antenna array to enhance the efficiency of Mobile Communications systems. It presents an overview of Mobile Communications as well as details of how an array may be used in various Mobile Communications systems, including land-Mobile, indoor-radio, and satellite-based systems. It discusses advantages of an array of antennas in a Mobile Communications system, highlights improvements that are possible by using multiple antennas compared to a single antenna in a system, and provides details on the feasibility of antenna arrays for Mobile Communications applications.
