초록 ▼

A method and apparatus minimize false detection of packet data in a receiver (202) due to noise in a communication system (100) utilizing time slots (420). Some time slots (420) contain a data packet (418), while others contain only noise. The data packet (418) includes a sync word (602) and an error-detecting code word (604, 606, 608). The receiver (202) is synchronized (1006, 1008) with a nominal predetermined timing of the time slots (420), and determines (1014) time windows (808) for receiving the data packets (418). During each of the time windows (808) data is received, demodulated, and stored (1016), and a predetermined portion of the data stored is searched (1018) to locate a point of maximum correlation between the data and a data template (902) matching the sync word (602). The data packet (418) is decoded (1020) by utilizing the point of maximum correlation as a reference, and the code word (604, 606, 608) of the data packet (418) is examined (1022, 1024) to determine whether the data packet (418) is valid or invalid.

A method for minimizing false detection of packet data in a receiver due to noise in a communication system utilizing data packet time slots that have a nominal predetermined timing for receipt, wherein some of the time slots contain a transmitted signal comprising a data packet, while others of the time slots contain only noise, and wherein the data packet comprises a sync word and an error-detecting code word, the method comprising the steps of: synchronizing the receiver with the nominal predetermined timing of the data packet time slots; determining, from the nominal predetermined timing and an expected range of transmission delays, a plurality of time windows during which transmitted data packets can be received at the receiver; receiving, demodulating, and storing data derived from the transmitted signal received during each of the plurality of time windows; searching a predetermined portion of the data stored during each of the plurality of time windows to locate a point of maximum correlation between the data and a data template matching the sync word; decoding the data packet throughout a data packet time slot by utilizing the point of maximum correlation as a reference; examining the error-detecting code word of the data packet decoded to determine whether the data packet is errored; and defining the data packet decoded to be a valid data packet if the data packet is not errored and to be an invalid data packet if the data packet is errored.
