Polyphase filter bank channelizer

WebDec 1, 2024 · The principle is that the receiving bandwidth is divided into several channels through a low-pass filter bank, then, the polyphase components of decimation filter and the lowpass filter are used as input of polyphase filter bank. Therefore, we can achieve low-speed data flow processing. WebThe dsp.Channelizer System object™ separates a broadband input signal into multiple narrow subbands using a fast Fourier transform (FFT)-based analysis filter bank. The filter bank uses a prototype lowpass filter and is implemented using a polyphase structure. You can specify the filter coefficients directly or through design parameters.
