Rate-Splitting Sparse Code Multiple Access

no code implementations26 Jan 2025 Minerva Priyadarsini, Kuntal Deka, Zilong Liu, Sujit Kumar Sahoo, Sanjeev Sharma

This paper presents a novel rate-splitting sparse code multiple access (RS-SCMA) framework, where common messages are transmitted using quadrature phase-shift keying (QPSK) modulation, while private messages are sent using SCMA encoding.

Generalized Spatial Modulation Aided Affine Frequency Division Multiplexing

no code implementations18 Jan 2025 Zeping Sui, Zilong Liu, Leila Musavian, Lie-Liang Yang, Lajos Hanzo

Generalized spatial modulation-aided affine frequency division multiplexing (GSM-AFDM) is conceived for reliable multiple-input multiple-output (MIMO) communications over doubly selective channels.

Uncovering Regional Defaults from Photorealistic Forests in Text-to-Image Generation with DALL-E 2

no code implementations3 Oct 2024 Zilong Liu, Krzysztof Janowicz, Kitty Currier, Meilin Shi

For a region in the hierarchy, our experiment reveals the regional defaults implicit in DALL-E 2, along with their scale-dependent nature and spatial relationships.
