A TRANSMIT POWER ALLOCATION METHOD FOR BIT ERROR RATE PERFORMANCE IMPROVEMENT IN MIMO OFDM SYSTEMS

摘要

A Tx power allocation method is provided to assign each transmission power, calculated according to each channel state, to each subcarrier of transmission antennas. A Tx power allocation method comprises the following steps. A receiving stage measures channel quality information of each channel, and then transmits the measured results to a transmitting stage(108). The transmitting stage calculates each transmission power which will be assigned to each subcarrier of transmission antennas according to each channel state, by using the transmitted channel quality information, and then assigns the each calculated transmission power to the subcarriers of transmission antennas(102).
