Hi all, I am trying to use Polyphase Clock Synchronization (PCS) block to conduct timing synchronization for QPSK signal with half-sine pulse shaping. In the doxygen document of PCS, it says that the "taps" parameter could be the matched filter. Thus, I put the matched filter of half-sine pulse here, [0,sin(pi/4),1,sin(3*pi/4)]. However, the output is all 0.
Is there anyone knows how to generate the "taps" parameter here? Any suggestion would be appreciated. Thanks in advance. Best regards, Su Li PS: here is my configuration for other parameters.
