A novel coordinated scheduling algorithm for OFDM-based systems in multi-cell scenario is proposed in this paper. The studied algorithm based on the utility function is general for the downlink of networks. The algorithm coordinates the subcarrier assignment over the BS cluster. We first establish the framework for this inter-cell coordinated optimization problem through utility-based method. The...
The Randomized Play-the-Winner (RPW) and the Generalized Friedman's Urn (GFU)model are very useful in clinical trials. In this paper, a new adaptive design is proposed which is beneficial for selecting the better of two competing treatments in future. It is more reasonable that the new design of two arms considers α and β belong to GFU model as parameters rather than constants. The new design has...
We compare the outage performance by applying transmit antenna selection strategies to amplify-and-forward protocol in the MIMO relaying scenario. Although antenna selection is a suboptimal form of beamforming, it enjoys the advantages of tractable optimization and low feedback overhead. Specifically, by combining transmit antenna selection strategies with amplify-and-forward protocol, we propose...
This paper is intended to serve as an introduction to the conceptual design of control system for a compact free electron laser (FEL) terahertz radiation source (FTRS). The general architecture of the control system is presented. The hardware components, software design, communications and subsystems are described in the paper. We also discuss a novel method of using Matlab Simulink\stateflow to simulate...
In this paper, we consider the unequal error protection (UEP) for progressive image transmission when the coded packet size is fixed. First, we prove that, for the source code with convex rate-distortion (R-D) function and practically used channel codes, the channel code rate for each packet in the optimal rate allocation is nondecreasing indeed. Then, we give an upper bound for the channel code rate...
