POWER CONTROLLING AND DEVICE THEREOF, TRANSREIEVER IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A power allocation method in a wireless communication system, a device thereof, and a transceiver adopting the same are provided to efficiently allocate the power to allow the transmission amount to be maximum. CONSTITUTION: A precoder(810) precodes a source bitstream through the multiply of a precoding matrix. The precoder provides the visual channel information to which the precoding matrix and the channel information are multiplied. A power control unit(816) receives the precoded value and the visual channel information. The power control unit allocates the power for each stream based on the virtual channel information so that the reception power or reception SNIR(Signal-to-Interference and Noise Ratio) and/or the reception SNR(Signal to Noise Ratio) may be maximum.
