Capacity of Sparse Wideband Channels with Partial Channel Feedback
Gautham Hariharan, Vasanthan Raghavan, Akbar M. Sayeed
This paper studies the ergodic capacity of wideband multipath channels with limited feedback. Our work builds on recent results that have established the possibility of significant…
On Precision - Redundancy Relation in the Design of Source Coding Algorithms
Yuriy Reznik
We study the effects of finite-precision representation of source's probabilities on the efficiency of classic source coding algorithms, such as Shannon, Gilbert-Moore, or arithmet…
Paging and Registration in Cellular Networks: Jointly Optimal Policies and an Iterative Algorithm
Bruce Hajek, Kevin Mitzel, Sichao Yang
This paper explores optimization of paging and registration policies in cellular networks. Motion is modeled as a discrete-time Markov process, and minimization of the discounted,…
Gaussian Interference Channel Capacity to Within One Bit
Raul Etkin, David Tse, Hua Wang
The capacity of the two-user Gaussian interference channel has been open for thirty years. The understanding on this problem has been limited. The best known achievable region is d…
Practical Binary Adaptive Block Coder
Yuriy A. Reznik
This paper describes design of a low-complexity algorithm for adaptive encoding/ decoding of binary sequences produced by memoryless sources. The algorithm implements universal blo…
