TRANSMITTING METHOD AND APPARATUS USING MIMO

摘要

PURPOSE: A space multiplexing transmission method and a device thereof are provided to control the transmission power for a transmission signal outputted from each amplifier to be equal. CONSTITUTION: A transmission power weight is given to each transmission signal(S510). A precoder precodes input signals to transmit a signal in a space multiplexing method through multi antenna system(S520). A precoded signals are transformed from a sequential transmission signal to a parallel transmission signal by a serial-parallel converter(S530). A transformed signal is inputted to an amplifier(S540).
