A METHOD OF REDUCING OVERHEAD FOR MULTI-INPUT, MULTI-OUTPUT TRANSMISSION SYSTEM

摘要

A method for reducing overhead in a multi input multi output transmitting system is provided to improve transmission efficiency by reducing the unnecessary data transmission. A primary antenna for transmitting a preamble is selected according to the satisfying state of at least one designated standard. The preamble is transmitted through the primary antenna. The overhead information is transmitted through the primary antenna. The overhead information includes pilot and medium access control.
