Joint Source-Channel Coding with Learnable Codebook Quantization for CSI Feedback

In this paper, we propose a joint source-channel coding (JSCC) framework with a learnable codebook quantizer (LCQ), termed JSCC-LCQ, for channel state information (CSI) feedback in frequency division duplex orthogonal frequency division multiplexing (FDD-OFDM) systems. Different from conventional codeword lookup or ind...

DuplexCadence: Exact State and Execution from a Speech Model's Declared Timelines

DuplexCadence is proposed, which explicitly declares native clocks to the runtime and derives two mutually enabling rules: demand-sized state allocation at a stable address, and exact-shape graph replay without padding, which eliminates idle memory and stabilizes tensor pointers.

G-SalAlignMamba: Geometry-Aware Vision Mamba for Dual-Modal Salient Object Detection

G-SalAlignMamba is proposed, a geometry-aware framework tailored for dual-modal SOD that introduces Geometry-Aware Encoding with explicit alignment to correct spatial shifts, Semantics-Informed Refinement to prevent signal dilution by prioritizing foregrounds, and Structure-Preserving Decoding that integrates explicit...
