Abstract

This paper makes use of the feature of space channel of the massive MIMO which means that the channel of each user in the beam domain focus on part of the beam to propose a kind of BDMA transmission. this paper takes advantage of the beam domain features of channel gain concentration to perform air separation multi-access transmission, In the Frequency division duplex (Frequency Division Duplexing, FDD) system, using the differences between channels, which will resolve the bottleneck of the pilot frequency brought by the massive antenna array in the mean time of matching the features of the massive MIMO system. The simulation directly at the downlink base SCM, thus considering that the base station uses only the beam selection transmission scheme where several antenna beams corresponding to its strongest direction are used to communicate with users. at last perform the simulation directly at the single user MIMO system user scheduling and characteristics of BRE which highlights the advantages of the algorithm.
