摘要
基于子载波功率方差(VSP)方法,提出一种结合信道化滤波器的抗干扰同步方法,以改善系统的同步性能.仿真实验和分析结果表明,当带内分布多源干扰信号时,该算法可以获得逼近于无干扰时的同步性能,且避免额外的信道均衡开销,能够有效适应共享频谱接入环境.
Based on the variance of subcarrier power(VSP) algorithm,an anti-jamming synchronization algorithm was proposed under the circumstances of multiple in-band interference signals with channelized pre-filtering.Simulation and analysis results indicate that the proposed algorithm can approach interference-free synchronization performance and avoid extra equalization expenditure,which is very suitable for overlay spectrum sharing access.
