大规模MIMO无线通信信道信息获取理论方法研究

Wireless large-scale multiple antenna (LSMA) systems that employ a sufficiently number of low-power antenna at the base station (BS) play a key role in fully exploiting spatial resources and improving the spectrum efficiency and power efficiency. LSMA technique is now considered as an inherent part of the future energy efficiency green wireless communication system. With the significantly increased antenna number of the BS, as well as the user number in the cell, the conventional channel state information (CSI) acquisition techniques can not be applied in LSMA systems. It is important to seek new CSI acquisition methods for LSMA systems. In this project, we design the synchronization signal, sounding signal, and pilot signal to acquire the synchronization information, statistical CSI, and instantaneous CSI, respectively. The main objective of this project is to form an integrated CSI acquisition technique for LSMA, which is essential to build an energy efficiency LSMA wireless communication systems.
