Method and apparatus for transmitting physical layer protocol data unit

An apparatus, comprising:

• at least one memory storing program instructions;
• and
• at least one processor coupled to the at least one memory, wherein the program instructions, upon being executed by the at least one processor, enable the apparatus to:
• generate a synchronization header field based on a third sequence, wherein the third sequence is:
• {−1, 0, −1, −1, 1, 1, 1, 1, 1, 1, 1, 0, −1, 1, 1, −1, −1, −1, 0, −1, −1, 1, −1, −1, −1, 1, −1, −1, −1, 0, 1, −1, −1, −1, 1, 1, −1, 1, −1, 1, 1, 1, −1, −1, 1, 0, −1, 1, 1, 1, 0, 0, 1, 0, −1, 1, 1, 1, 1, 1, −1, 1, −−1, −1, 1, 0, 1, 1, −1, −1, 1, 1, 1, 1, −1, −1, −1, 1, −1, 1, 1, −1, 1, −1, 1, 1, −1, −1, 1, 1, 1, 1, −1, −1, −1, 1, 0, −1, 1, 1, −1, 1, 1, −1, 1, 1, 1, −1, 1, −1, 1, −1, 1, −1, 1, −1, 1, 1, 1, 1, −1, 0, −1, −1, 1, 0, 1, 1, −1, 1, −1, −1, −1};
