Simulation of mobile-to-mobile radio fading channels
2005 12th IEEE International Conference on Electronics, Circuits and Systems, 2005In this paper, we discuss the applicability of deterministic parameter computation methods to the design of simulation models for mobile-to-mobile multipath fading channels. It is shown that the Rice's sum-of-sinusoids concept, employing the mean square error method (MSEM), the Lp-norm method (LPNM) and the method of exact Doppler spread (MEDS) can ...

Journal of the Institution of Electronic and Radio Engineers, 1987
After a brief historical survey of radio telephony developments, the paper first looks at the present position of mobile radio, particularly paging, cordless telephone and cellular services. Consideration is then given to the rapid technological developments in electronic components and circuits (particularly digital technology) and the miniaturization

IEEE Communications Magazine, 1991
Following a brief prologue and historical overview, such technical issues as the repertoire of systems and services, management of the airwaves, the operating environment, service quality, network issues and cell size, channel coding and modulation, speech coding, diversity, multiplex, and multiple access (FDMA, TDMA, CDMA) are discussed.

Mobile radio traffic consideration
31st IEEE Vehicular Technology Conference, 1981In a trunked mobile radio system a number of mobiles or stations in a "fleet" (user) communicate with their respective "dispatcher" or among themselves using a number of radio channels common to other users. The literature to date has attempted to characterize the subtle differences between this sort of trunked system with that found in telephone ...

Packetizing voice for mobile radio [PDF]
IEEE Transactions on Communications, 1994 In present mobile radio systems, conventional FM techniques are used to transmit speech in its analog form. A number of digital schemes have been proposed in the past as an alternative. To overcome the effects of Rayleigh fades that appear in the received speech as noise bursts in the form of "pops" and "clicks", the author proposes packetizing speech ...

The Mobilization of Weimar Radio
Transfers, 2013This essay addresses the effects and experiences that become possible, and become the object of fascination and reflection, when early German radio mobilized-when it moved out of the studio to transmit from places in the "outside world." Mobile electro-acoustic technologies enabled a new sense of exteriority and new experiences of time and space.

Mobility Model for Multimedia Mobile Radio Network
2003The aim of this work is to develop a mobility and traffic model for multimedia mobile radio networks. These models are developed according to measures from two considered service areas and they analyzed by simulation. Users issue multimedia calls which are to be managed according to a traffic model.
