We propose a framework for cooperative spectrum sensing in cognitive radio (CR) networks with adaptive energy threshold control for local spectrum sensing and an efficient approach for data fusion. Each secondary user (SU) carries out energy detection based local spectrum sensing, where the energy threshold is adaptively adjusted in real time according to both the SINR (signal to interference plus...
In multi-channel wireless communications, Water-Filling (WF) is a fundamental power allocation mechanism for capacity maximization under a given total transmit power. In this letter, we propose simple and fast WF algorithms for achieving agile power allocation, such that the system can better match the dynamic nature of the wireless channels for a better performance. Our algorithms remove the need...
The moisture control for sinter mixture is always a difficulty in industry. This paper presents a modeling for the Pb-Zn sintering process of Imperial Smelting Process(ISP), which is to solve the modeling of permeability and parameters of sintering technical. An intelligent system for controlling moisture of sinter mixture based on ABPM artificial neural network is developed for the purpose. The BP...
