Yes, you guessed right somehow I left the word zero out. > So I used the source, Luke, and > > 1. these are not the resamplers you're looking for (probably), unless > you're really going for non-rational ($\frac1\pi$) or really > really-close-to-1 ratios, and > 2. the point where the phase delay is implemented is by using the MMSE > interpolator[1], which really is just a set of FIRs, from which the > right one is selected by definition of the µ to use. I have not selected this resampler by myself and just recognised some weird behaviour in the channel model block. I have just ran some tests and it seems there is not just a delay: (again resampling rate=1.0 phase offset=0) First five input samples: [(1+0j), (0.9980267284282716+0.06279051952931337j), (0.9921147013144779+0.12533323356430426j), (0.9822872507286887+0.18738131458572463j), (0.9685831611286311+0.2486898871648548j)] First five output samples: ((0.9822872281074524+0.187381312251091j), (0.9685831665992737+0.24868988990783691j), (0.9510565400123596+0.30901700258255005j), (0.9297764897346497+0.3681245446205139j), (0.9048270583152771+0.4257792830467224j)) A delay would be something I expect but completely removing samples? Is it possible the first 3 samples are used to initialize the filter? Maybe I can also dig through the source but not until evening. Regards, Andrej
