Covert Multi-bit LLM Watermarking: An Information Theory and Coding Approach
Sidong Guo, Tyler Kann, Teodora Baluta +1
We study the problem of multi-bit watermarking for large language models (LLMs). We introduce a block-autoregressive model inspired by multi-token prediction, in which the encoder…

Designing Affine OCDM Systems with Maximum Diversity
Sidong Guo, Xiaoli Ma, Yiyin Wang
This work considers the problem of enabling maximum multipath diversity of orthogonal chirp division multiplexing (OCDM)-based systems. We define and study an Affine OCDM (A-OCDM)…
