| 摘 要： | 文章提出一种利用OFDM调制实现同时使用多个频点进行跳频的多载波跳频通信系统，并给出了一种基于RS序列的多载波跳频方案。通过计算机仿真，对多载波跳频信号进行时／频分析，验证了多载波跳频机制，并给出了高斯白噪声下系统的BER曲线。根据OFDM调制的特点，其非常方便使用FPGA器件实现。文章最后给出一个简单的多载波跳频通信的FPGA实现。

| Abstract: | This paper introduced a frequency hopping mechanism using multiple carriers at a time based on the OFDM modulation. The hopping pattern used in this mechanism was at basis of the theory of RS coding. The computer simulation analyzed the signals generated in time and frequency domain, and the result validated the multi-carrier frequency hopping mechanism. The BER curves varying with Eb/N0 was also given to show the performanee of this system anti AWGN. |
