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。
A new two-channel channel optimization design method is proposed. Based on the existing two-channel FIR filter bank design method, the proposed method achieves a better performance channel controller by reducing the optimization of the stop-band energy. The numerical simulation shows that the stopband attenuation of each filter in the channelizer is effectively increased, and a high performance two-channel software radio channelizer is obtained.
