WebJun 16, 2016 · So the 2X interpolation is done in the Physical Layer Framer block instead. You can remove the zero stuffing from the Physical Layer Framer and use the Interpolating FIR Filter block instead of the FFT filter block for RRC filtering. If you try that, be sure to remove the factor of two in lines 535, 548 and 680 in the PL framer block.

WebMar 7, 2011 · RRC Filter Taps with 16 samples per symbole, and 176 (11*sps) taps. The symbol rate is thus set to samp_rate / sps, and the gain to sps**0.5 to compensate for the filters, Interpolating FIR Filter and Decimating FIR Filter using the defined taps and respectively set with interpolation to sps and decimation to sps, WebIn general, there are L polyphase filters. Having the designed interpolation filter H ( z) of N taps, we can determine each bank of filter coefficients as follows: (11.12) For our example, L = 2 and N = 4, we have L − 1 = 1, and N / L − 1 = 1, respectively. Hence, there are two filter banks, ρ0 ( z) and ρ1 ( z ), each having a length of 2 ... charged jump ue5 https://gmaaa.net

WebAug 4, 2016 · That's a ratio of: 20000000 / 480000 ≈ 41.666. We can't decimate by fractional samples, so we must write that as a ratio of integers: 20000000 480000 = 500 12. GNU Radio's low-pass filter block can perform decimation but not interpolation, so we can refactor that fraction as: 20000000 480000 = 100 1 ⋅ 5 12. Since 5 is prime, that 5/12 ...
