Performance of frame synchronization in packet transmission using bit erasure information

The probability of successful frame sync in packet transmission using bit erasure information is compared to the same probability when erasure information is ignored. For a given bound on the false alarms, a significant improvement is found on additive white Gaussian noise (AWGN) channels if an erasure zone is added to the receiver. An improvement is also found for channels in which the presence of jamming or other interference is detected and erased by the receiver. An expression for the probability of frame synchronization in packet transmission is derived as a function of the bit error and erasure probability, the amount of overlap, and the number of bit errors/erasures which are tolerated in the frame sync word
