In this paper, a distributed Dual-Ring Tree scatternet formation is proposed to generate a reliable topology for Bluetooth networks. To mitigate the formation complexity, each root distributively connects with its downstream roots with local topology instead of global nodes information, instructs them to connect together, and generates a desired dual-ring subnet via distributed computation with three...
This paper proposes a novel LQ-based generalized side-information cancellation (GSIC) precoder for multiuser multi-input multi-output (MU-MIMO) downlink systems with sum-rate performance enhancement. The proposed transceiver comprises the following stages. First, a unitary transform matrix designed through the LQ decomposition of the MU-MIMO channel is proposed for suppressing MU interference and...
The algorithms of Delaunay triangulation are the main algorithms when establishing DEM. The algorithm of going forward beginning with margins has been improved in two ways after some researches are made on several Delaunay triangulation algorithms. On the one hand, edges are directly used as the base when going forward, other than using Voronoi figure as the base. On the other hand, data set partition...
Focused ultrasound thermal therapy relies on temperature monitoring for treatment guidance and assurance of targeting and dose control; a potential approach to achieve these is ultrasonic temperature estimation. The approach used currently involves the detection of echo time shifts based on cross-correlation processing from the segmented radio-frequency (RF) data. In this study, we propose a novel...
This paper proposes a new approach to designing alternate routing algorithms for all-optical wavelength-division multiplexing networks in order to reduce the connection blocking probability. The key idea is to try to route traffic in approximately the optimal way of splitting the traffic among the multiple routing paths between each source-destination pair. The optimal way of splitting the traffic...
