【摘要】 提出一种新的两通道信道器优化设计方法。该方法以现有两通道FIR滤波器组设计方法为基础,通过减小阻带能量的优化算法得到性能更好的信道器。数值仿真表明,有效地增加了信道器中各滤波器的阻带衰减,得到高性能的两通道软件无线电信道器。更多还原

【Abstract】 This paper proposed a new optimization method of two-channel channelizer.The method was based on an existing design scheme in the literature for initialization,and got better performance by minimizing stopband energies of the filterbanks.Numerical simulation could prove that the method increased the attenuation of each filter,obtained efficient two-channel channelizer for software radio.更多还原
