摘要

智能电网是电力系统未来的发展方向，但传统的数据无线电台已难以满足新的业务需求。本研究结合最新的多载波通信技术，设计了一种无线通信系统，以提高传输速率和系统可靠性，实现智能电网的信息和交互。该系统首先根据230MHz信道的特点，通过加窗组和滤波组分别对OFDM和GFDM中的信号进行优化，从而实现对发射机相邻信道干扰的抑制。另一方面，为了更好地适应信道条件的变化，引入了自适应调制编码方案(AMC)。采用Turbo码，通过仿真得到了不同调制和编码方案的传输效率。采用Okamura-Hata模型对230MHz频段进行了计算，得到了不同编码速率和场景下小区的覆盖范围和相应的系统性能。

Multicarrier transmission design for wireless communication in smart grid

Smart grid is the future development direction of power system, but it is difficult for the traditional data radio station to meet the new business needs. In this study, a wireless communication system combining the latest multicarrier communication technology is designed to improve the transmission rate and system reliability to realize information and interaction of smart grid. The system first respectively optimizes the signals in OFDM and GFDM by windowing and filter banks according to the characteristics of 230MHz channel, so as to realize the suppression of adjacent channel interference at the transmitter. On the other hand, in order to better adapt to the change of the channel conditions, we introduce the adaptive modulation and coding scheme (AMC). Turbo code is used and the transmission efficiency of different modulation and coding schemes is obtained by simulation. Using the Okamura-Hata model for the 230MHz band, we obtain the coverage of the cell and the corresponding system performance with different coding rates and scenarios.
