On the Capacity Region of the Gaussian Z-channel
"... Abstract — We investigate the capacity region of the Gaussian Z-channel with a small crossover link gain, i.e., α ≤ 1. Forthe case of α<1, we provide an achievable region, and the converse for most of the achievable region. We also derive lower and upper bounds for the part of the region where th ..."

An Inequality on the Capacity Region of
, 1994
"... The effects of multiaccess sources and time varying multipath are considered in analyzing a system in which multiple sources communicate with a fixed base station. We discuss detection and the use of stripping in a multiaccess multipath environment. We finally derive a capacity for these systems. It ..."

On the Computation of the Capacity Region of the Discrete MAC
"... Abstract—The computation of the channel capacity of discrete memoryless channels is a convex problem that can be effi-ciently solved using the Arimoto-Blahut (AB) iterative algorithm. However, the extension of this algorithm to the computation of capacity regions of multiterminal networks is not str ..."

Gaussian multiaccess channels with ISI: Capacity region and multiuser water-filling
- IEEE Trans. Inform. Theory
, 1993
"... Abstract-The capacity region of a two-user Gaussian multiac-cess channel with intersymbol interference (ISI), where the inputs pass through respective linear systems and are then superimposed before being corrupted by an additive Gaussian noise process, is found. A novel geometrical method is given ..."

The Capacity Region of Gaussian Broadcast Channels with Intersymbol Interference
- IEEE Trans. Inf. Th
, 2001
"... We derive the two-user capacity region with and without common information for a Gaussian broadcast channel with intersymbol interference, assuming colored Gaussian noise and an input power constraint. The proof is achieved by first defining a similar channel model, the circular broadcast channel, w ..."

Duality, achievable rates, and sum-rate capacity of Gaussian MIMO broadcast channels
- IEEE TRANS. INFORM. THEORY
, 2003
"... We consider a multiuser multiple-input multiple-output (MIMO) Gaussian broadcast channel (BC), where the transmitter and receivers have multiple antennas. Since the MIMO BC is in general a nondegraded BC, its capacity region remains an unsolved problem. In this paper, we establish a duality between ..."

Secrecy capacity region of fading broadcast channels
- in Proc. of IEEE International Symposium on Information Theory (ISIT
, 2007
"... Abstract — The fading broadcast channel with confidential messages (BCC) is investigated, where a source node has common information for two receivers (receivers 1 and 2), and has confidential information intended only for receiver 1. The confidential information needs to be kept as secret as possib ..."

capacity region is first established for the parallel Gaussian BCC, and the optimal source power allocations that achieve the boundary of the secrecy capacity region are derived. In particular, the secrecy capacity region is established for the Gaussian case of the Csiszár-Körner BCC model. The secrecy
