Abstract
The present invention relates to a communication system and method for transmitting sync flags and pilot symbols during sync symbol periods. Example embodiments provide a method for sharing sync symbols to communicate flag sequences and pilot sequences during a sequence of sync symbol periods. The method includes modulating the pilot sequence by multiplying a pilot code by each value of the pilot sequence, and modulating the flag sequence by multiplying a flag code by each value of the flag sequence. The pilot and flag codes are mutually orthogonal to each other and each includes at least two non-zero values. The method further includes generating a resulting sync symbol sequence based on the modulated pilot sequence and modulated flag sequence, and sending the resulting sync symbol sequence during the sync symbol period.
