High-Speed Mobile Communications in Hostile Environments
With the inexorable increase in the use of mobile devices, wireless connectivity is expected by users anywhere, anytime. In general, this requirement is addressed in office buildings or public locations through the use of Wi-Fi technology but Wi-Fi is not well adapted for use in large experiment halls and complex underground environments, especially those where radiation exposure is an issue, s...
متن کاملBandwidth Efficient Turbo Coding for High Speed Mobile Satellite Communications
This paper describes an application of turbo codes in conjunction with 16QAM in high speed mobile satellite communications. The channel characteristics, the architecture of the modem and the performance curves for the selected turbo codes are presented.
متن کاملAn integrated OFDM receiver for high-speed mobile data communications
In this paper, we present the system design of an integrated receiver for the next generation high-speed mobile data communications based on OFDM. First an overview of the OFDM system suitable for mobile communications is described. The effects of non-ideal transmission conditions of the OFDM system including channel estimation errors, symbol timing offset, carrier and sampling clock offset, ph...
متن کاملSemi-blind equalization for high speed GMSK-based mobile communications
This paper is concerned with semi-blind equalization techniques applied to bursty GMSK-based mobile communication systems. In bursty time-division multiple access mobile communication systems, the standards specify a maximum relative speed between transmitter and receiver at a given carrier frequency. However, in practical situations the maximum Doppler spread resulting from these maximum relat...
متن کاملSecure Transactions with Mobile Agents in Hostile Environments
A major problem of mobile agents is their apparent inability to authenticate transactions in hostile environments. In this paper, we consider a framework for the prevention of agent tampering without compromising the mobility or autonomy of the agent. Our approach uses encrypted functions. We present an RSA implementation which answers affirmatively the open problem on undetachable signatures o...
