Abstract
PURPOSE: A reference signal transmission method for a multiple antenna system and a device thereof are provided to improve system performance by selective channel estimation of robust frequency through multiplexing of reference signal. CONSTITUTION: A terminal(900) comprises a reference signal generator(910), an OFDM symbol generating unit(920), and an RF unit(930). The reference signal generator creates multiple reference signal sequences. The OFDM symbol generating unit is connected to the reference signal generator. The OFDM symbol generating unit creates the OFDM symbol mapped with multiple reference signal sequences. The RF part is connected to the OFDM symbol generating unit. The RF unit transmits OFDM symbol to the base station through a plurality of antennae(990-1, .,990-N).
