METHOD AND APPARATUS FOR GENERATION AND USAGE OF EXTENDED GOLAY CODES
First Claim
1. A method of communication, comprising:
- obtaining an extended Golay code selected from a set of extended Golay codes generated from a Golay code and a set of short sequences, said extended Golay codes having zero periodic cross-correlation; and
generating a preamble using the extended Golay code.

Abstract
A wireless device comprises a code-assignment module configured for assigning Golay codes to be used for spreading, a spreading module configured for spreading data with the Golay codes to produce a signal, wherein the Golay codes are randomly used to spread the data, and a transmitter configured for transmitting the signal. The wireless device may transmit a first beacon signal via a set of quasi-omni beam patterns, and a second beacon signal via a set directional beam patterns. The first beacon signal has a first transmission rate that is higher than the second beacon signal'"'"'s the transmission rate. Extended Golay codes having zero periodic cross-correlation may be generated from a Golay code and a set of short sequences. A data block transmitted by the wireless device may comprise Golay codes and data portions, wherein every data portion is between two Golay codes and every Golay code is between two data portions.
