英文摘要: With the increasing of the mobile data service, the scarcity of the spectral resource, and the rapid increasing of the energy consumption, it gives highly demand to improve the performance of beyond 4G mobile communication systems. Then, the innovation of the wireless transmission techniques are needed to solve the spectral efficiency and power efficiency, and achieve the targets of higher spectral efficiency and green wireless communications. When the base station are equipped with a very large number of antennas, massive MIMO are established, the spectral efficiency and power efficiency can be improved greatly. Then, massive MIMO techniques are received much attention in recent years. In this project, we will study the transmission theory and techniques of massive MIMO: firstly, using information theory, we will give the theoretical analysis of the spectral efficiency and power efficiency of massive MIMO, and review the impact of the system parameters and channel parameters on the system performance; secondly, we will study the downlink precoding and uplink joint receiver to overcome the complexity of the massive MIMO, we will also study the techniques to overcome the pilot contamination and inter-cell interference, and then the complete transmission theory and technique systems of the massive MIMO will be es
