Subject: | Re: [Discuss-gnuradio] Polyphase Clock Synchronization with Matched Filter |
Date: | Mon, 27 Apr 2015 15:34:37 +0200 |
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.
