Compression Techniques Vs Huffman Coding

, 2015
The technique for compressioning the Images has been increasing because the fresh images need large amounts of disk space. It is seems to be a big disadvantage during transmission & storage of image.

PAPR Reduction Using Huffman and Arithmetic Coding Techniques in F-OFDM System [PDF]

, 2018
Filtered orthogonal frequency division multiplexing (F-OFDM) was introduced to overcome the high side lobes in the OFDM system. Filtering is implemented in the system to reduce the out-of-band emission (OOBE) for the spectrum utilization and to meet the ...

Early Labor Market Outcomes of Young Adults From Same‐Sex Families: Evidence From Population Data

Journal of Marriage and Family, EarlyView.
ABSTRACT Objective This study offers the first population‐based evidence on how young adults from same‐sex families fare when entering the labor market shortly after leaving full‐time education. Background Same‐sex couples' parenting rights remain controversial in many countries.

Entropy Coding Aided Adaptive Subcarrier-Index Modulated OFDM

IEEE Access, 2018
We propose entropy coding-aided adaptive subcarrier-index-modulated orthogonal frequency division multiplexing (SIM-OFDM). In conventional SIM-OFDM, the indices of the subcarriers activated are capable of conveying extra information. We propose the novel

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Class-dependent and differential Huffman coding of compressed feature parameters for distributed speech recognition

, 2009
In this paper, we propose an entropy coding method for compressing quantized mel-frequency cepstral coefficients (MFCCs) used for distributed speech recognition (DSR).

Impact‐diagnostic criteria for use in confirming a meteorite impact origin of terrestrial geological structures: Recommendations by the Impact Cratering Committee of the Meteoritical Society

Meteoritics &Planetary Science, EarlyView.
Abstract The framework of the Impact Cratering Committee (ICC) of the Meteoritical Society was approved in 2020, with the first committee members appointed in 2023. The ICC has a mandate to (1) approve, maintain, and update a database of confirmed terrestrial meteorite impact structures, (2) define and regularly update the criteria used for ...

The Renyi redundancy of generalized Huffman codes [PDF]

IEEE Transactions on Information Theory, 1988
If optimality is measured by average codeword length, Huffman's algorithm gives optimal codes, and the redundancy can be measured as the difference between the average codeword length and Shannon's entropy. If the objective function is replaced by an exponentially weighted average, then a simple modification of Huffman's algorithm gives optimal codes ...

Equal Time, Unequal Labor Division: Adolescents' Domestic Labor Time During the COVID‐19 Pandemic

Sociological Inquiry, EarlyView.
While existing research offers mixed evidence on how the COVID‐19 pandemic affected adults' division of housework, adolescents have remained largely overlooked in this regard. Using nationally representative data from the 2019–2021 American Time Use Survey and Current Population Survey, this study examines changes in adolescents' unpaid labor before ...
