Recently, cooperative communication is shown to be a promising approach to achieve spatial diversity. The performance improvement by cooperative communication heavily depends on selecting suitable relay node. Therefore, designing effective relay assignment algorithm becomes critical in wireless cooperative networks. Although many studies focus on relay assignment problem, none of them concerns the...
The paper is about how to evaluate the intelligent knowledge. We think that the criteria is not only distinguishing ability and accuracy of the algorithm, but also algorithm robustness, stability and so on. Besides positive characters listed above, a fair evaluation system of intelligent knowledge should also include negative characters, such as storage space, running time, training and testing time...
In wireless sensor networks, balanced energy dissipation is crucial to achieving satisfactory network lifetime. Since all data packets usually have to be forwarded to the base station via multi-hop routing, the traffic pattern is highly non-uniform, putting a high burden on the sensor nodes close to the base station. This paper proposes novel centralized and distributed algorithms to efficiently balance...
To extract parameters of the received signal correctly in the digital radio mondiale (DRM) system, robustness mode detection must be accomplished in time domain. Based on the cyclic prefix (CP), this paper presents a robustness mode detection algorithm in the DRM system. Using the system parameters of each robustness mode separately, the linear-weighted correlation and global maximum correlation-value...
