| Abstract(in English) | Massive MIMO transmission, whose number of antennas is much larger than the number of user terminals, has been attracted much attention as one of key technologies in next-generation mobile communication system, because it enables improvement in the service area and interference mitigation by the simple signal processing. Multi-beam massive MIMO configuration has proposed that utilizes the beam selection with high power in an analog part and blind algorithm such as constant modulus algorithm (CMA) which does not need channel state information (CSI) is applied in a digital part. Hence, the proposed configuration obtains high transmission efficiency. We have evaluated the performance with two kinds of user selection methods using only recieved power of the multi-beams in the uplink channel. In this report, we propose a new user selection method which combines two methods to improve the performance, and its performance is evaluated by the computer simulation. |
