摘要
该文介绍了一种改进的通信测距复合系统,即应用自适应组合滤波器和Gardner于1986年的基于循环谱分析法的SPECCORR_TDOA估计模型,来改进系统的抗窄带干扰和高斯白噪声的能力,并建立了系统仿真平台.同时提出了应用'峰值比'对复合系统的抗干扰能力进行评估.仿真结果证明,改进的复合系统具有强抗干扰能力.
A novel model of the multiplex system is proposed, which can suppress narrowband interference and white Gaussian noise by using adaptive combination filter and estimation model of SPECCORR_TDOA based on analyses of cyclostationary signals. Finally, the multiplex system models are simulated with computer. The result proves that the improved multiplex system has strong suppression ability of interference and noise.
