Differential Properties of Information in Jump-diffusion Channels (2501.05708v6)
Published 10 Jan 2025 in cs.IT and math.IT
Abstract: We propose a channel modeling using jump-diffusion processes, and study the differential properties of entropy and mutual information. By utilizing the Kramers-Moyal and Kolmogorov-Feller equations, we express the mutual information between the input and the output in series and integral forms, presented by Fisher-type information and mismatched KL divergence. We extend de Bruijn's identity and the I-MMSE relation to encompass general Markov processes.
