ABSTRACT:
A channel scanning communication receiver (204) operates in a system that transmits information in cycles (104) including subsequences (106). The receiver determines whether to operate in a scanning or locked mode by making (302) signal quality pass/fail decisions for subsequences transmitted in a predetermined group of cycles. A decision is made for a transmission of a subsequence, and subsequence active/inactive decisions are made (304) for the subsequences transmitted in the predetermined group of cycles, based upon the signal quality pass/fail decisions made for the subsequences. The receiver determines (306) whether the system is time-shared or continuous, based upon how many active decisions and inactive decisions are made, and selects (310, 312) the scanning or locked mode in accordance with predetermined rules for time-shared or continuous systems, according to whether the system is time-shared or continuous.
