The focus of this proposal on devising energy efficient communication scheme for massive multiple-input multiple-output (MIMO) systems, also known as very large scale MIMO. Massive MIMO has been recently the center focus of research due to its potential to provide data rate gains in the order of few thousands. The basic idea in massive MIMO to equip the base stations with a large number of antennas, while the user devices have only one single antenna, thereby allowing very sharp beams to be formed from the base stations towards the users (downlink) and vice versa (uplink). In the project we will develop robust signal processing techniques using worst-case optimization techniques. These techniques will guarantee that the performance will not worse than certain level under two assumptions, 1) the energy efficiency is maximal 2) the CSI is bound to be within a norm-bounded set.

该方案的重点是设计海量多输入的节能通信方案 多输出(MIMO)系统，也称为超大规模MIMO。大规模MIMO最近已经成为 研究的中心焦点 由于其提供几千量级的数据速率增益的潜力。大规模MIMO中的基本思想是 为基站配备大量天线，而用户设备只有一根天线， 从而允许 从基站向用户形成非常尖锐的波束(下行链路)，反之亦然(上行链路)。 在该项目中，我们将使用最坏情况下的优化技术来开发稳健的信号处理技术。 这些技术将保证在两个假设下性能不会低于一定的水平， 1)能量效率是最大的；2)CSI必然在范数有界集内。
