This paper proposes an output power smoothing control strategy for the wind farm without any other energy storage devices (ESS), which is based on the allocation and control of the wind turbines (WT). The wind turbines in the wind farm are divided into control wind turbines (CWT) and power wind turbines (PWT) separately while playing different roles. The PWTs are expected to output as much power as...
This paper investigates the ergodic secrecy capacity (ESC) of multiple-antenna amplify-and-forward relay systems, where one eavesdropper can wiretap the relay. To reveal the capability of the multiple- antenna relay in improving the secrecy performance, we derive new tight closed-form lower bounds of the ESC for two secure transmission schemes: artificial noise aided precoding (ANP) and eigen-beamforming...
Device-to-Device (D2D) is considered as a promising technique to improve resource utilization and provide new application in future wireless networks. This paper addresses the problem of radio resource allocation for D2D communication. Basically, resource allocation can be carried out in centralized or distributed manner. In this paper we discuss the mechanisms of distributed resource allocation and...
As a kind of intelligent component, text classification plays an important role in Business Intelligence (BI) application such as client opinion classification, market feedback analysis and so on. Latent Dirichlet Allocation (LDA) model, which is a kind of excellent text representation model, has been widely used in various document processing applications. However, its performance is affected by...
We consider a parallel relay communication network based on the nonorthorgonal amplify-and-forward protocol. We design two optimal power allocation schemes: separate power allocation (SPA) of the relays using the improved water-filling algorithm and joint power allocation (JPA) of the source and relays using convex optimization algorithm. Simulation results show that, in the fading channels with path...
This paper discusses resource management system of netted radar focusing on all the controllable resources in the network, and designs an effective architecture which includes resource management function, information management function, service management function, radar control function and efficiency analysis function. The proposed architecture is comprehensive and systematic for realization and...
In this paper, new dynamic resource allocation algorithms are presented for the downlink of multi-user MIMO-OFDMA/SDMA systems. Since it is difficult to obtain the optimal solution to the joint optimization problem, the whole procedure is divided into two steps, namely, the subcarrier-user scheduling and the resource allocation. In the first step, a new metric is proposed to measure the spatial compatibility...
