摘要

尽管正交频分复用(OFDM)系统具有比单载波通信系统更强的抗干扰能力，但当基于OFDM的无线通信系统中存在特定的干扰或干扰信号时，将给通信带来严重的问题。因此，设计针对这种干扰的对策是非常重要的。本文介绍了在强频谱集中干扰(SCI)下基于OFDM的纠错编码系统。将权函数与非线性补偿方法相结合，可以提高系统抗SCI的鲁棒性。提出并比较了几种窗函数。计算机仿真显示了信号频谱的改进。

Interference-Robust OFDM Communication System using Weight Functions

When there is any particular interference or jamming signal in the OFDM based wireless communication system, it will be serious problem for the communication even though OFDM (orthogonal frequency division multiplexing) system is inherently robust to interference than the single carrier communication system. Therefore, it is very important to design the counter-measure to this kind of interference. This paper describes OFDM based system with error correction coding in presence of strong spectral concentrated interference (SCI). Using weight function in combination with nonlinear compensation method allows to increase robust against SCI. Several window functions are proposed and compared. Computer simulation shows the signal spectrum improvements.
