Abstract
In a communications system having transmissions containing certain information-of-interest at predetermined intervals in the transmission, there is provided a method for isolating and processing that information-of-interest. The method comprises sensing the start of a transmission and isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission. Thus, the information-of-interest is isolated principally on the basis of elapsed time. The method for isolating and processing that information-of-interest is further characterized by sensing the start of a transmission from the received signal power of the transmission exceeding a predetermined threshold; AGCing the transmission and attenuating the AGC'd transmission from a maximum level to a desired level before the information-of-interest is expected to arrive; isolating for processing as the information-of-interest, the information received about instant(s) predeterminally removed in time from the sensed start of transmission, by timing the expected interval between the instant that the start of the transmission is sensed and the predetermined instant that the information-in-interest should arrive (whereby the information-of-interest is isolated principally on the basis of elapsed time); tagging the information isolated about that instant for processing; and beginning processing with information just preceeding the isolated information (whereby the reliability of the information detection is enhanced by one-to-several bits).
