Patent ID: 8073072

Claim:
A method of transmitting a time-division training pattern for multiple-input multiple-output packets, the method comprising the steps of: transmitting a short symbol by a first antenna and a second antenna, the short symbol being split between a predetermined set of short bins, wherein the first antenna is associated with a first set of short bins and the second antenna is associated with a second set of short bins; transmitting a long symbol substantially simultaneously by the first antenna and the second antenna after transmission of the short symbol, the long symbol associated with a first set of long bins and a second set of long bins, wherein the first antenna transmits using the first set of long bins before using the second set of long bins, and wherein the second antenna transmits using the second set of long bins before using the first set of long bins; and transmitting SIGNAL symbols associated with multiple-input multiple-output data substantially simultaneously by the first antenna and the second antenna after transmission of the long symbol.
