中文摘要：

根据跳频信号与部分频带噪声阻塞干扰信号的近似统计独立性，提出一种基于盲源分离的跳频通信对抗部分频带噪声阻塞干扰方法。所提方法利用分离信号的二阶或高阶统计量构建目标函数引导分离矩阵迭代，实现跳频信号与部分频带噪声阻塞干扰信号的有效分离，从而提高跳频通信的抗干扰能力。仿真结果表明，所提方法可明显改善跳频通信在部分频带噪声阻塞干扰下的误码率性能，而且分离算法的处理时延很小，有望满足跳频通信的实际需求。

英文摘要：

According to the approximately statistical independence between the frequency hopping （FH） signal and the partial-band noise jamming （PBNJ） signal, a blind source separation （BSS） based anti-jamming method for FH communication against PBNJ is proposed. The object function is constructed with the second or- der statistics or the higher order statistics of the separated signals. The unmixing matrix is calculated through the iterations which are induced by the object function. Then, the separation between the FH signal and the PBNJ signal is achieved, and the anti-jamming ability of FH communication is enhanced. Simulation results in- dicate the proposed method can improve the bit error rate of FH communication greatly when the PBNJ signal exists. The processing delays of the separation algorithm are very small. And the proposed method can satisfy the practical demand of FH communication well.
