Signal Decoding Problems


#1

Hey,
I’m trying to decode a Enocean signal, but can’t link the received data
to the corresponding byte sequence, which was decoded by an Enocean
receiver.
Following the Enocean specifications the signal (attached) is
ASK-modulated with 125 kbit/s data rate. The Enocean protocol refers to
ISO Standard 14543-3-10:2012, but as a student I can’t afford 130€ for
the document.

After computing the magnitude of the signal (attached) and mapping to 0
or 1 (attached), the MM clock recovery produces the attached bit
sequence.

I verified the MM generated bit sequence by reading the bits manually
out of the magnitude view. The sequence and signal edges are also
fitting in the 125 kbit/s frequency. Because the timing is covering the
signal edges instead of the high & lows, it can’t be Manchester encoded
(or am I wrong?).

This bit sequence is produced by my flow graph:
101010101101010011010101110111011101110001011101101011010101101000101101110010101010

While the official Enocean reciever is producing this output:
0007,07,01,7A,F610018313E12001FFFFFFFF3100,07

Does someone has a clue, how the signal is modulated to produce these
data?
