Abstract:
1. A method for sharing sync symbols to communicate flag sequences and pilot sequences during a sequence of sync symbol periods, the method comprising: modulating the pilot sequence by multiplying a pilot code by each value of the pilot sequence to form an encoded pilot sequence; modulating the flag sequence by multiplying a flag code by each value of the flag sequence to form an encoded flag sequence, the pilot and flag codes being mutually orthogonal to each other, the pilot and flag codes each including at least two non-zero values; generating a resulting sync symbol sequence based on the encoded pilot sequence and encoded flag sequence such that each value of the encoded pilot sequence and each value of the encoded flag sequence affects more than one sync symbol in the resulting sync symbol sequence; and sending the resulting sync symbol sequence during the sequence of sync symbol periods.
