摘要
多载波扩频(MC-SS)技术结合了OFDM和扩频技术的优点,具有很强的抗干扰能力。MC-SS系统、MC-DS-SS系统和MT-SS系统是3种主要的多载波扩频系统。而部分频带干扰是一种常见的干扰类型。在介绍几种主要的多载波扩频系统的基础上,分析了多载波扩频系统的抗部分频带干扰的能力,给出了在干扰信息状态(JSI)已知和未知状态下的误码率。
Multicarrier spread spectnnn (MC-SS) technology combines the advantages of OFDM and SS technology,and has good performance of anti-jamming. MC-SS, MC-DS-SS and MT-SS system are three kinds of main multicarrier spread spectrum systems, Partial-band jamming is a familiar type of jamming. Based on instruction of several kinds of main MC-SS systems, this paper analyses the performance of anti partial-band jamming. BERs in the cases of jamming sate information (JSI) being known and unknown are given.
