Abstract: PURPOSE: An apparatus and a method for transmitting multiple antenna having power constraint for each antenna are provided to transmit a signal using multiple antennae having a power constraint for each antenna. CONSTITUTION: A control unit(412) repetitively performs a precoding algorithm based on each antenna. The control unit sequentially updates a precoder for each of multiple antennae in each repetition. The control unit determines the precoding algorithm converges based on variation of data rate of transmission information through the overall repetition. If convergence of the precoding algorithm is determined, a precoding unit(406) precodes signals using the precoding algorithm. A plurality of the antennae transmits the precoded signals.
