UWB脉冲设计与窄带干扰抑制
为了避免对频带内已有的窄带通信系统造成干扰,在进行波形设计时,如果能使UWB脉冲在干扰频带内的能量下降,即在窄带通信系统的工作频带内实现陷波,则可达到抑制窄带干扰的目的。-UWB pulse design and narrow-band interference suppression in order to avoid the narrow band communication systems has been caused by interference,

分析了相位噪声对正交频分复用(OFDM)系统的影响,发现相位噪声不仅产生
通用相角错误(CPE),而且还会产生载波间干扰(ICI),这都使OFDM系统的性能急剧恶
化,因此必须对CPE和ICI进行校正.文中给出了基于MSE准则的CPE校正方法,考虑到
ICI干扰主要来源于相邻信道,进而提出了基于LMS法则的自适应相邻信道干扰消除方
