Hi Mike,
Not sure if you've still got this question, but the problem is that
the output of sample_framer + bytes_to_syms can't be directly
connected to simple_correlator. The simple correlator exepects its
input to be oversampled 8x times. Just wiring them together as you
have doesn't honor that requirement.
