Abstract(in English) Massive MIMO (Multiple-Input Multiple-Output) which is an enlarged view of transmitting and receiving antenna 100 element scale is required for highly accurate channel information to achieve a fast and reliable data transmission. In the case of using a general channel estimation, it is necessary to send the same number of reference signal and the transmission antenna, because the proportion of communication recouse for use in data transmission is reduced. In this paper, we propose a signal detection method of applying the new channel estimation method. Moreover, we evaluate the bit error rate performance by computer simulations.
