Flow Decomposition
Jonathan Ponniah, Liang-Liang Xie
The decode-forward achievable region is studied for general networks. The region is subject to a fundamental tension in which nodes individually benefit at the expense of others. T…
An Achievable Rate Region for the Two-Way Multiple-Relay Channel
Jonathan Ponniah, Liang-Liang Xie
We propose an achievable rate-region for the two-way multiple-relay channel using decode-and-forward block Markovian coding. We identify a conflict between the information flow in…
A Unified Relay Framework with both D-F and C-F Relay Nodes
Xiugang Wu, Liang-Liang Xie
Decode-and-forward (D-F) and compress-and-forward (C-F) are two fundamentally different relay strategies proposed by (Cover and El Gamal, 1979). Individually, either of them has be…
On the Optimal Compressions in the Compress-and-Forward Relay Schemes
Xiugang Wu, Liang-Liang Xie
..... joint decoding provides more freedom in choosing the compression at the relay. However, the question remains whether this freedom of selecting the compression necessarily imp…
Asymptotic Equipartition Property of Output when Rate is above Capacity
Xiugang Wu, Liang-Liang Xie
The output distribution, when rate is above capacity, is investigated. It is shown that there is an asymptotic equipartition property (AEP) of the typical output sequences, indepen…
An Improvement of Cover/El Gamal's Compress-and-Forward Relay Scheme
Liang-Liang Xie
The compress-and-forward relay scheme developed by (Cover and El Gamal, 1979) is improved with a modification on the decoding process. The improvement follows as a result of realiz…
A Greedy Omnidirectional Relay Scheme
Liang-Liang Xie
A greedy omnidirectional relay scheme is developed, and the corresponding achievable rate region is obtained for the all-source all-cast problem. The discussions are first based on…
Omnidirectional Relay in Wireless Networks
Liang-Liang Xie
For wireless networks with multiple sources, an omnidirectional relay scheme is developed, where each node can simultaneously relay different messages in different directions. This…
On Information-Theoretic Scaling Laws for Wireless Networks
Liang-Liang Xie
With the analysis of the hierarchical scheme, the potential influence of the pre-constant in deriving scaling laws is exposed. It is found that a modified hierarchical scheme can a…
