A new tone reservation (TR) scheme for the Peak-to-average power ratio (PAPR) reduction in the orthogonal frequency division multiplexing (OFDM) system is proposed. Different from the conventional TR scheme, the cancellation signals are generated by using FFT/IFFT iteration. Simulation results show that the new TR scheme based on FFT/IFFT has a perfect PAPR reduction performance and the number of...
The forecasting of disaster weather, especially intensive convective weather, is becoming increasingly important. Recent evidence has indicated that the intensive precipitation in the Changjiang River Basin and the south-west region of China is closely related to the activity of Mesoscale Convective Systems (MCS), which move out of the Tibetan Plateau in China. To date, however, the mechanism of MCS...
Original kernel machines (e.g., support vector machine, least squares support vector machine, kernel Fisher discriminant analysis, kernel perceptron algorithm, and etc.) were mainly designed for binary classification. How to effectively extend them for multiclass classification is still an ongoing research issue. Rosenblatt's linear perceptron algorithm for binary classification and its corresponding...
