Modified SNR Gap Approximation for Resource Allocation in LDPC-Coded Multicarrier Systems
IEEE Access, 2020 The signal-to-noise ratio (SNR) gap approximation provides a closed-form expression for the SNR required for a coded modulation system to achieve a given target error performance for a given constellation size. This approximation has been widely used for

Combined Source-Channel Coding of Images under Power and Bandwidth Constraints
EURASIP Journal on Advances in Signal Processing, 2007 This paper proposes a framework for combined source-channel coding for a power and bandwidth constrained noisy channel. The framework is applied to progressive image transmission using constant envelope M-ary phase shift key (M-PSK) signaling over an ...

Super-orthogonal trellis-coded spatial modulation
IET Communications, 2012 Spatial modulation (SM), which employs the indices of multiple transmit antennas to transmit information in addition to the conventional M-ary signal constellations, is a novel transmission technique that has been proposed for multiple-input multiple-output systems.

New Phytologist, Volume 248, Issue 1, Page 178-192, October 2025.Summary While grapevine is an exceptional perennial model for studying host‐microbiome interactions, the host genome's role in microbiome assembly is often masked by environmental factors. This research provides a first insight into the genetic mechanisms shaping berry‐associated microbial communities.
