摘要
在通信系统中,干扰抑制是一项基本的工作,对系统的稳定性起到重要的作用。详细讨论了关于线性预测技术在直扩系统中自适应抗窄带干扰的应用。理论仿真和实际验证结果表明,能够有效地抑制多个较强的窄带干扰,提高了系统的稳定性。此外,该算法资源消耗较少,工程实现容易,因此具有很强的实用性。
The interference suppressions is an essential measure and plays a great role in the stability of communication systems. In this paper, the application of the linear prediction technology for suppressing the multiple narrowband interference (NBI) in direct sequence spread spectrum (DSSS) systems is discussed in detail. Simulation and verification results show that it can suppress multiple strong narrowband interference and improve the stability of the systems. What's more, the scheme is very easy to implement with low FPGA and suits for applications.
