Tree structured hybrid filter banks based on power complementary pairs

  • 摘要: 提出了一种近似完全重构的树形结构混合滤波器组(HFB)的设计方法,利用基于功率互补对的树形结构的模拟分解滤波器,而非传统的低通、带通和高通分解滤波器均匀分割整个系统带宽.采用遗传算法实现了功率互补对的优化设计,并基于逆快速傅立叶变换(IFFT)实现了数字综合滤波器的设计以保证近似完全重构.3阶和5阶的功率互补对与63阶的数字FIR(有限冲击响应)综合滤波器所组成的四通道混合滤波器组,具有1.06×10-7dB平均失真误差和-111 dB的平均混叠误差,满足15 bit的模数转换(ADC)系统要求.
