Energy efficient transmission techniques for LTE

IEEE Communications Magazine, 2013
The goal of the European ICT Project EARTH is to enhance energy efficiency of current LTE cellular networks by 50 percent, enabling operators to provide more extensive coverage, namely to less densely populated areas, while ensuring high levels of efficiency, hence, reducing the carbon footprint. In order to achieve this objective, different strategies,

Energy-efficient compressed address transmission

18th International Conference on VLSI Design held jointly with 4th International Conference on Embedded Systems Design, 2005
To realize energy-efficient buses in current nanometer-scale technologies, techniques like compression or encoding that exploit information redundancy have been explored. However, available compression techniques for buses do not always ensure energy-efficient transmission of compressed information.

Transmission and the Determinants of Transmission Efficiency

2014
Bacteria within the order Rickettsiales would have little impact on human and veterinary medicine in the absence of the arthropod vector. Interestingly, the influence of primary infections with one Rickettsia sp. can influence the success of transovarial transmission of a second.

A bandwidth efficient OFDM transmission scheme

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
In this paper, a new bandwidth efficient OFDM transmission scheme is proposed. A bandwidth efficient iterative scheme for OFDM systems without using cyclic prefix was proposed before [3] which works well when a channel does not have a deep spectral null. But such a frequency domain deep null is common in a wireless channel. A bandwidth efficient scheme

Efficient transmission of halftones via facsimile

Journal of Electronic Imaging, 1996
The conventional method for sending halftone images via facsimile machines is inefficient. The previously proposed Tone- Fac algorithm improves the transmission of halftone images. Tone- Fac represents a halftone image by mean gray values of the disjoint blocks and an error image, which records the difference between the desired halftone and the ...

A High Spectrum Efficiency Transmission Scheme

2009 International Conference on Scalable Computing and Communications; Eighth International Conference on Embedded Computing, 2009
In order to improve the transmission performance in inter-symbol interference channel, a controlled inter-symbol overlapping transmission scheme to obtain high frequency efficiency, which is called inter-symbol overlapping transmission (ISOT), is studied. ISOT allows $K$ symbols to be simultaneously transmitted without increasing channel bandwidth, and

A Secure Transmission Scheme Based on Efficient Transmission Fountain Code

2020 IEEE/CIC International Conference on Communications in China (ICCC), 2020
Improving the security of data transmission in wireless channels is a key and challenging problem in wireless communication. This paper presents a data security transmission scheme based on high efficiency fountain code. If the legitimate receiver can decode all the original files before the eavesdropper, it can guarantee the safe transmission of the ...

Efficient storage and transmission of ladar imagery

Applied Optics, 2003
We develop novel methods for compressing volumetric imagery that has been generated by single-platform (mobile) range sensors. We exploit the correlation structure inherent in multiple views in order to improve compression efficiency. We show that, for lossless compression, three-dimensional volumes compress more efficiently than two-dimensional (2D ...

Energy-efficient transmission with data sharing

2015 IEEE Conference on Computer Communications (INFOCOM), 2015
In a wireless system, when multiple applications can share data transmitted by rate-adaptive wireless devices, there exists a trade-off between transmission redundancy and energy efficiency. This paper conducts the first theoretical analysis on such a trade-off.
