WebJul 22, 2024 · The FPGA clock rate cannot run at the sample rate, so the samples are streamed in parallel (4 samples per clock cycle). I'd like to design a polyphase decimation filter to split the input spectrum into 4 downsampled subbands, with an effective rate of fs/4 per "channel". In that way, for each subband channel, there's only 1 sample per FPGA ... WebLearn more about serdes, digital comminication, feedforward equalizer, filter, equalization, pam4 MATLAB, SerDes Toolbox.

The Variable FIR Decimation block performs an efficient polyphase FIR decimation with a tunable decimation factor. You can update the decimation factor and the filter coefficients in the block dialog box or through an input port while the simulation is running. Conceptually, the FIR decimator (as shown in the schematic) consists of ...
