Using radar to detect multiple high-speed targets is a process that can be equivalently expressed by detection of multiple linear frequency modulation signals. In this paper, preliminary detection is performed on multiple signals using short-time Fourier transformation (STFT) and then the preliminary detection results are treated using binaryzation, during which the phase information of the signals...
In order to maximize system capacity in a dual-hop regenerative relay system under certain power cost, the concept of power price is proposed, which is determined by the different fashions of power supply at the nodes, and power cost is defined explicitly. According to the analysis below, the allocation of power cost is determined by the channel gains and power prices, and the system capacity is formulated...
In order to control the interference, and improve the spectral efficiency in the Femtocell and Macrocell Overlaid System (FMOS), the FMOS model is built and Combination of Frequency bandwidth dynamic division and Clustering Algorithm (CFCA) is proposed for Orthogonal Frequency Division Multiple Access (OFDMA) FMOS. In CFCA, the optimal clustering problem in terms of interference mitigation is constructed...
In order to reduce power cost in regenerative relaying system, the concept of power price is proposed, which determined by the different fashions of power supply at the nodes. An algorithm is proposed to minimize the outage probability based on power price, which subjects to the constraint of power cost. Lagrange multiplier maximization method is used to solve this problem. Numerical results show...
The performance of relay is often measured by ergodic capacity and outage capacity. In comparison,Outage capacity is more appropriate measure for channel quality in wireless communication system. Although outage capacity has been mentioned in some literature, but no research has been clearly revealed outage capacity of DF dual-hop relay. In this paper, we obtain a constraint equation of outage capacity...
