FRAME TRANSMITTING AND RECEIVING METHOD BY CHANNEL ESTIMATION IN MULTIPLE INPUT MULTIPLE OUTPUT WIRELESS COMMUNICATION SYSTEM

摘要

For communicating data frames, a respective data frame is transmitted from each of a plurality of transmitter antennas of a transmitter. In addition, a power of any data field that is of a predetermined data type within the respective data frames is boosted to a maximum available power of the transmitter. Thus, total available power of a transmitter is efficiently used for transmitting data fields of the predetermined data type such as channel estimation preambles transmitted with time orthogonality.
