Differential Binary Phase Shift Keying (DBPSK) parameter extraction results.

Each message frame begins with an 8-bit Barker sequence [11100010] for frame synchronization.
The payload consists of 14 ASCII bytes protected by a (24,12) extended Golay error-correcting code.

When all 14 rows are assembled, the matrix forms an 80-column ASCII status report.

Every song on SYNTHESIS was engineered to be exactly long enough to transmit one complete telemetry frame.
