Capacity Bounds and Mapping Design for Binary Symmetric Relay Channels
Entropy, 2012 Capacity bounds for a three-node binary symmetric relay channel with orthogonal components at the destination are studied. The cut-set upper bound and the rates achievable using decode-and-forward (DF), partial DF and compress-and-forward (CF) relaying ...

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 It is greatly significant to achieve radar forward-looking region imaging. Due to the limitation of phase ambiguity and small Doppler gradient in forward-looking region, synthetic aperture radar and Doppler beam sharpening cannot work for forward-looking

Achievable Rate Regions for Two-Way Relay Channel using Nested Lattice Coding [PDF]
, 2013 This paper studies Gaussian Two-Way Relay Channel where two communication nodes exchange messages with each other via a relay. It is assumed that all nodes operate in half duplex mode without any direct link between the communication nodes.

SVD Entropy Reveals the High Complexity of Ecological Networks
Frontiers in Ecology and Evolution, 2021 Quantifying the complexity of ecological networks has remained elusive. Primarily, complexity has been defined on the basis of the structural (or behavioural) complexity of the system.

Approximate Multiplier based on Low power and reduced latency with Modified LSB design [PDF]
E3S Web of Conferences, 2023 The devised approximation multiplier can adapt the precision and processing power needed formul triplication sat run-time based on the needs of the user. To decrease error distance, we also suggest a straight forward error compensation circuit. There are

Perbandingan Kinerja Non-Orthogonal dan Orthogonal Amplify and Forward pada Two-Way Cooperative WLAN
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2017 Nowadays, the advancement of Wireless Local Area Network (WLAN) technology has developed very rapidly because it is very practical and has effective mobility level. In practice, there is a major problem in wireless communications systems, which is fading.

Lossless Image Steganography Based on Invertible Neural Networks
Entropy, 2022 Image steganography is a scheme that hides secret information in a cover image without being perceived. Most of the existing steganography methods are more concerned about the visual similarity between the stego image and the cover image, and they ignore

Nonlinear Behavior of High-Intensity Ultrasound Propagation in an Ideal Fluid
Acoustics, 2020 In this paper, nonlinearity associated with intense ultrasound is studied by using the one-dimensional motion of nonlinear shock wave in an ideal fluid. In nonlinear acoustics, the wave speed of different segments of a waveform is different, which causes
