[0072] In order to make the purpose, technical solutions and advantages of the present invention clearer, specific examples are listed below to further describe the present invention in detail.
[0073] The present invention provides a method for completing frame synchronization in a burst communication system, comprising: performing segmental coherent correlation operations with different segment lengths on the received data frame (received signal sequence) at the initial channel access stage; The judgment method determines the starting position of the initial detection frame; the confirmation window mechanism is used to determine the starting position of the final detection frame; the stable communication phase uses different segmentation methods, double threshold thresholds, search window length and confirmation window length from the initial channel access phase; In the case of periodic beacon frames, the frame synchronization position with the highest probability of occurr...
