针对高速移动环境下的通信特点,提出了一种基于FBMC-OQAM系统的方法用于抑制干扰。该方法以FBMC技术为基础,通过引入OQAM调制实现了全速率正交传输,用于增强系统对频偏的鲁棒性。结果表明,该方法能够在高速移动的环境下,有效消除多径信道中的干扰和衰落,提高误码率和系统性能。

For communication characteristics in high-speed mobile environments, a method of FBMC-OQAM system is proposed to suppress interference. The method is based on FBMC technology, and full rate orthogonal transmission is achieved by introducing OQAM modulation to enhance the robustness of the system to frequency offset. As the results is shown, the proposed method can eliminate the interference and fading in multipath channels effectively, and improve the bit error rate and system performance in a high-speed mobile environment.
