You aren't missing anything, you just need to account for the possible rotation. The easy way to do this is with differential decoding, because the instantaneous phase is irrelevant. The harder-but-still-easy was is to transmit some know sequence at the beginning to determine the phase offset and adjust your decoding accordingly.
