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…
Phase-Resolved Molecular Timing Channels under Pulsatile Drift: Volterra Characterization and Corrected Inverse-Gaussian Approximation
Yen-Chi Lee
Pulsatile drift makes molecular arrival times depend on the release phase. We study a one-dimensional absorbing timing channel with constant diffusivity and positive-mean sinusoida…
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 where absorption occurs (the first-hitting location, or FHL) as a primary boundary observable…
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…
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…
