Adaptive data rate capacity of meteor-burst communications
IEEE Conference on Military Communications, 2002The use of adaptive data rates in the meteor-burst communications environment is investigated. Measured results obtained from a number of meteor links are presented and compared with previous theoretical predictions. The contribution of various meteor trail families to throughput capacity are also investigated. The results show that the use of adaptive

Adaptive coverage for high data rate LTE networks
2014 International Conference on Computing, Networking and Communications (ICNC), 2014Traditional cellular network infrastructure provide fixed radio coverage. The temporal changes in user distribution throughout the day and from day to day leads to inefficient use of radio resources. Our position is to create an adaptive radio coverage to match the radio resources and user demand. The main approach for creating flexible radio coverage (

A rate-adaptive protocol for wireless data channels
2000 IEEE Wireless Communications and Networking Conference. Conference Record (Cat. No.00TH8540), 2002We present a simple heuristic protocol for adaptively adjusting the rate of an error correcting code so as to match the time-varying error probabilities in a slowly fading channel. Channel state is estimated from the past error history. Analysis and simulations indicate excellent performance over a wide variety of channels.

Adaptive variable rate data transmission over fading channel with adaptive feedback equalization
Conference Record of the Thirty-Fourth Asilomar Conference on Signals, Systems and Computers (Cat. No.00CH37154), 2002We investigate by simulation the possibility of joint usage of decision feedback equalization and adaptive control of symbol duration under the data transmission over Rayleigh fading channel. The findings show that the contribution essentially mitigates the burst error effect caused by the equalization.

Adaptive multi-code CDMA systems for variable data rates
1997 IEEE International Conference on Personal Wireless Communications (Cat. No.97TH8338), 2002To increase the spectrum efficiency in mobile communications and to support variable data rates, multi-code code division multiple access (MC-CDMA) systems have been proposed which allow to support variable source data rates by variation of the set of code sequences assigned to every user.

Rate adaptation for bursty data transmission in CDMA networks
Conference Record of Thirty-Fifth Asilomar Conference on Signals, Systems and Computers (Cat.No.01CH37256), 2001We study rate adaptation for the uplink of CDMA networks with many ON/OFF data users. We propose a novel multi-access interference (MAI) model that takes into account simultaneously the burstiness of data traffic and time-varying fading. We characterize the MAI from a stochastic process perspective.

Adapting the VLT data flow system for handling high-data rates
SPIE Proceedings, 2004The Data Flow System (DFS) for the ESO VLT provides a global approach to handle the flow of science related data in the VLT environment. It is a distributed system composed of a collection of components for preparation and scheduling of observations, archiving of data, pipeline data reduction and quality control.

Adaptive data rate transmission between vehicle and access point
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015Recent, as interest in the vehicle communication is high, various techniques have been developed. However, the vehicle communication has a problem due to high-speed mobility of vehicle. Especially V2I (Vehicle-to-Infrastructure) communication has a biggest problem that is deterioration of continuity and reliability caused by frequent hand-off with base
