摘要/Abstract

摘要： 本文提出一种基于快速计算余弦调制滤波器组(CMFB)和正弦调制滤波器组(SMFB)联合谱估计的变换域抗干扰算法.与已有的CMFB抗干扰算法比较,本算法不仅消除了信号相位对幅度谱估计的影响,而且增强了对短周期平稳干扰的抑制能力.为增加工程可实现性,本文补充改进Malvar提出的CMFB快速计算算法,得到快速计算CMFB和SMFB结构,并应用于提出的抗干扰算法.仿真和资源分析表明,在误码率性能相近且子滤波器数足够时,提出的算法乘法和加法运算量分别仅为基于重叠相加DFT抗干扰算法的75%和45%.

Abstract: A Transform Domain Anti-Interference Method based on fast algorithm Cosine Modulated Filter Banks (CMFB) and Sine Modulated Filter Banks (SMFB) combining spectrum estimation is proposed.Compared with existing CMFB Transform Domain Anti-Interference Method,this method not only avoids the signal phase effect on the amplitude spectrum,but also enhances the excision capacity of short periodic stationary signals.For increasing the technical realization,fast algorithm structures of CMFB and SMFB are obtained by improving and supplementing the CMFB fast algorithm by Malvar,and then used to the proposed Anti-Interference method.The simulation and recourse analysis confirm that the multiplication and the addition of the proposed Method are just 75% and 45% of the overlapped-and-add DFT Anti-Interference Method,when the bit error rate performances are close to each other and sub-filters are enough.

Key words: transform domain anti-interference, cosine modulated filter banks (CMFB), fast algorithm
