With the rapid development of electrical network construction, it is an urgent need to solve the problem of reasonably planning AC and DC transmission voltage class sequence in the transmission network. As the major object of study, the applicable range of AC and DC transmission mode and their voltage class sequence is explored in this paper. Firstly, the fast establishing method of AC is proposed...
In this paper, a new suboptimal tone reservation (TR) algorithm with fixed phase rotation method based on Constant Amplitude Zero Auto-Correlation (CAZAC) sequence is proposed to reduce peak-to-average power ratio (PAPR) in multicarrier code division multiple access (MC-CDMA) systems. To decrease tone searching complexity of TR method, CAZAC sequences is utilized as initial tone candidates. To reduce...
In recent days, cooperative diversity and communication security become important research issues for wireless communications. In this paper, to achieve low probability of interception (LPI) and high throughput in the cooperative single-carrier frequency division multiple access (SC-FDMA) system, a new physical layer transmission scheme is proposed, where a new encryption algorithm is applied and...
The wind power data have very strong nonlinearity and non-stationarity, but the traditional method mainly focuses on the nonlinear problem of the wind power data and doesn't analysis the non-stationary problem. This paper proposed the combining method of atomic sparse decomposition and artificial neural network (ANN) to research the short-term forecasting of the wind power. Firstly, wind power data...
