Gnuradio polyphase filter bank
WebThe following slides describe the regular polyphase filter bank, the transpose form FIR filter, and optimizations based on symmetry This is a symmetric FIR filter, i.e., the first n/2 and the last n/2 coeffs are the same, albeit in reverse order. We can exploit this symmetry to implement an optimal form of the filter bank, using resource sharing. WebJun 24, 2015 · I think your polyphase filter bank approach has the brightest future (basically because I think polyphase filter banks are cool, and because they are really quite efficient), but your filter parameters are frightening: A transition bandwidth of 10kHz at a sampling rate of 25MHz is 0.04% transition width, which leads to a filter of more than ...

WebWith every polyphase filter bank I have worked with, the first block in the analysis phase is an IFFT, and the block in the synthesis phase is a DFT. These operations essentially cancel one other, so it should be fairly intuitive. WebWith the Theseus Cores v1.1.0 release, we now support a highly requested feature for the polyphase channelizer: FPGA-based channel selection and deinterleaving. While I wont go into too much detail on the M/2 polyphase filter bank (PFB) FPGA implementation, I’d like to cover some of the more advanced RFNoC and GNU Radio tricks used here.
