WebAug 10, 2024 · So the document seems to specify a raised-cosine filter, both on the transmit and receive side; so not a ROOT raised-cosine as is used in most PSK systems. Question: How do I create the filter-taps for the Polyphase clock sync block for a raised-cosine filter? I found a function firdes.root_raised_cosine, but no firdes.raised_cosine? WebUnlike the raised-cosine filter, the impulse response is not zero at the intervals of ±T s. However, the combined transmit and receive filters form a raised-cosine filter which does have zero at the intervals of ±T s. Only in the case of β=0 does the root raised-cosine have zeros at ±T s.
