Oh... thanks for that! I wasn't aware of it. I will try to modify it later, but after a first inspection, I see I will need to fill the preamble not only modulated by square-gaussian pulses, but also modulated by frequency, and use this block with base band signal instead of Quadrature Demod outpu

Hi to all. I want to test if the block Correlate and Sync improves my GFSK receiver, so I started modifying ./gr-digital/examples/demod/test_corr_and_sync.grc . 1) I replaced the BPSK modulator (with rrc filter) by a Chunks to Symbols [-1,+1] followed by a Interpolating FIR with gaussian taps. 2)
