A Novel Scheme for Enhancing Antijamming Capabilities of Spread Spectrum Communication Systems

本文提出了一种用于提高扩谱通讯系统抗干扰能力的新方案。方案中采用了DS/FH混合式扩谱系统去增大系统的处理增益;采用了可调微波滤波器以降低系统的瞬时带宽。文中还提出了用软限幅器代替硬限幅器,以避免中间调制问题。

A novel scheme for enhancing antijamming capabilities of spread spectrum communication systems is proposed in the paper. It employs DS / FH hybrid systems and comprises following major components: a low-noise wideband tunable microwave amplifier, a tunable microwave bandpass filter, and a soft limiter. It is shown that the scheme make it possible to increase the antijamming capabilities of spread spectrum communication systems significantly.
