The Corrected Inverse-Gaussian: A Tractable First-Hitting-Time Channel Model for Nonstationary Molecular Communication
Yen-Chi Lee
This paper develops a tractable analytical channel model for first-hitting-time molecular communication (MC) systems under time-varying drift. While existing studies of nonstationa…
On the Tail Transition of First Arrival Position Channels: From Cauchy to Exponential Decay
Yen-Chi Lee
While the zero-drift first arrival position (FAP) channel exhibits a Cauchy-distributed lateral displacement, nonzero drift in practical systems introduces advective transport that…
First-Hitting Location Laws as Boundary Observables of Drift-Diffusion Processes
Yen-Chi Lee
First-passage theory usually emphasizes when absorption occurs. Here we instead treat the location where absorption occurs, called the first-hitting location (FHL), as a primary bo…
Exact 3-D Channel Impulse Response Under Uniform Drift for Absorbing Spherical Receivers
Yen-Chi Lee, Ping-Cheng Yeh, Chia-Han Lee
An exact channel impulse response (CIR) for the three-dimensional point-to-sphere absorbing channel under drift has remained unavailable due to symmetry breaking. This letter close…
Capacity Scaling Laws for Boundary-Induced Drift-Diffusion Noise Channels
Yen-Chi Lee
This paper studies the high-power capacity scaling of additive noise channels whose noise arises from the first-hitting location of a multidimensional drift-diffusion process on an…
