ABSTRACT:
Whether to indicate reception of an access code in a receiver operating in a communications system is determined by receiving a signal and generating a correlation value by correlating the received signal with a reference code. A threshold level is set to a first value if the receiver is in a scan mode. The threshold level is set to a second value if the receiver is in a traffic mode, wherein the second value corresponds to a lower degree of correlation than the first value. The correlation value is compared with the threshold level. Reception of the access code is indicated only if the correlation value compares favorably with the threshold level.
