Gaussian Broadcast Channels Orthogonal Bidirectional Cooperation Link
2010/11/24
This paper considers a system where one transmitter broadcasts a single common message to two receivers linked by a bidirectional cooperation channel, which is assumed to be orthogonal to the downlin...
The Capacity of the Semi-Deterministic Cognitive Interference Channel and its Application to Constant Gap Results for the Gaussian Channel
ThCapacity Semi-Deterministic Cognitive Interference Channel Application to Constant Gap Results
2010/12/7
The cognitive interference channel (C-IFC) consists of a classical two-user interference channel in which the message of one user (the “primary” user) is non-causally available at
the transmitter of ...

A Liminf Result on Two-parameter Gaussian Process
fractional wiener process increments liminfs
2007/12/10
In this paper, a liminf behavior is studied of a two-parameter Gaussian process which is a generalization of a two-parameter Wiener process. The results improve on the liminfs in [7].
Factors of the Gaussian Coefficients

2014/6/3
There are many reasons for the Gaussian coefficients (or the q-binomial coefficients) to be polynomials. We show that the divisibility directly follows from the basic properties of cyclotomic polynomi...
We show that the formalism of overpartitions gives a simple involution for the product de nition of the Gaussian coefficients. In the formulation of our involution, an overline in the representation o...
