When an initial frame alignment during decoding of multi-frame data
segments fails a cyclic parity check, a portion of the received data is
retained and reused for a second decode attempt using a different frame
alignment. For BCH data transmitted within a WCDMA system, the second of
two frames received and failing a parity check on decode is retained and
coupled with a third received frame for a second decode attempt. When
incorrect frame alignment is the cause of failure of the first decode
attempt, the correct frame alignment should be achieved using the second
and third received frames. Recovery from initial incorrect frame
alignment is thus quicker than systems discarding all data from the first
decode attempt.
