Probabilistic Temporal Shaping for Level-Constrained Signaling on Bandlimited Additive White Gaussian Noise Channels
Mahdi Mahvari, Gerhard Kramer, Shlomo Shamai
Level-constraints model one-bit-quantized signaling over real-alphabet continuous-time channels. New lower bounds on the capacity of bandlimited, additive white Gaussian noise chan…

Stability of the Ghurye-Olkin Characterization of Vector Gaussian Distributions
Mahdi Mahvari, Gerhard Kramer
The stability of the Ghurye-Olkin (GO) characterization of Gaussian vectors is analyzed using a partition of the vectors into equivalence classes defined by their matrix factors. T…
