Energy Efficient Transmission over Space Shift Keying Modulated MIMO Channels [PDF]
Energy-efficient communication using a class of spatial modulation (SM) that encodes the source information entirely in the antenna indices is considered in this paper. The energy-efficient modulation design is formulated as a convex optimization problem,

Comparative analysis of code execution time by C and Python based on selected algorithms
The article deals with a comparative analysis of the speed of code execution written in the C language and Python. In order to determine whether a scripting language can match the performance of a compiled language, a comparison of the languages was ...

Fast and efficient lossless encoder in image compression with low computation and low memory
This research focuses on frequency‐based lossless new encoding technique with low computation and low memory scheme. This encoding technique doesn't require, any table similar to Huffman and Golomb Rice encoder, and doesn't take high computation time ...

Using Probabilistic Models for Data Compression
Our research objective is to improve the Huffman coding efficiency by adjusting the data using a Poisson distribution, which avoids the undefined entropies too. The scientific value added by our paper consists in the fact of minimizing the average length

Enhanced Huffman Coded OFDM with \\Index Modulation [PDF]
<pre>In this paper, we propose an enhanced Huffman coded orthogonal frequency-division multiplexing with index modulation (EHC-OFDM-IM) scheme. The proposed scheme is capable of utilizing all legitimate subcarrier activation patterns (SAPs) and adapting the bijective mapping relation between SAPs and leaves on a given Huffman tree according to ...

A quantum analog of Huffman coding [PDF]
We analyze a generalization of Huffman coding to the quantum case. In particular, we notice various difficulties in using instantaneous codes for quantum communication.

HUBFIRE - A multi-class SVM based JPEG steganalysis using HBCL statistics and FR Index [PDF]
Blind Steganalysis attempts to detect steganographic data without prior knowledge of either the embedding algorithm or the 'cover' image. This paper proposes new features for JPEG blind steganalysis using a combination of Huffman Bit Code Length (HBCL ...
