Energy Efficient Transmission over Space Shift Keying Modulated MIMO Channels [PDF]
, 2012 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,

Using Probabilistic Models for Data Compression
Mathematics, 2022 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
