抑制UWB系统中窄带干扰的频谱空洞编码方法
Mathod to Suppress NBI in UWB Based on Spectral Nulls Codes
本文提出了一种新颖的UWB传输信号功率谱成形技术,即通过频谱空洞编码方法,使最终产生的UWB传输信号功率谱密度在一确定频率处产生谱空洞,从而避免了来自现有窄带系统的干扰,通过改变编码参数,从而改变谱空洞的位置和宽度,以达到所需的窄带抑制效果,本文详细地给出了该方法的理论分析,并利用计算机仿真验证了该方法的正确性。
n ultra-wideband (UWB)spectrum shaping approach was presented in order to introduce spectralls to avoid interference with narrowband signals.By employing Spectral Nulls Code(SNC),the PSD of transmitted coded UWB signal will be with spectral nulls at interference frequency bands.Using different parameters of SNC can obtain differrent suppressions.
