Abstract：A method of reducing the computation complexity of a base-stations channelizer is presented in this paper.Through using a interpolated second-order polynomials(ISOP)filter to shape the Inverse Discrete Fourier Transform(IDFT) filter bank,the IDFT filter bank can be used as a base stations channelizer directly.The complexity of implementing this channelizer is lower,so it is suitable to be used in base stations implemented with software radio technique.Theoretical analysis and simulation result show that with the system performance remains almost fixed this method is 17% more efficient than the Open-Filter-Bank(OFB) channelizer proposed by K.C.Zangi in implementing the channel filter.
