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.
