A Dual Polyphase Decomposition Overlapped Polyphase Filter Bank and Its Implementation in a Field-programmable Gate Array

A Dual Polyphase Decomposition Overlapped Polyphase Filter Bank and Its Implementation in a Field-programmable Gate Array

Real-time processing of ultra-wideband signals requires dividing them into several subbands by using a channelizer filter such as a polyphase filter bank. Original channelizers, like the critically sampling polyphase filter bank (CSPFB), face issues such as subband edge attenuation and spectral alia...
