Abstract
A receiver synchronization control in signalling messages in TACS/AMPS system in a mobile phone is disclosed. In order to avoid unnecessary setting of hunt mode operation, if the received synchronization pattern is not congruent with the correct reference pattern, the received pattern is checked in a bit-by-bit manner so as to reveal occasional bit errors of one or two bits, which may appear although the receiver is in synchronization. A further check may be conducted by shifting a reference pattern mask by one or at the most two bits in either direction, whereafter rechecking to reveal either fully correct pattern or rechecking for only one or two bits error can be performed.
