Pilot Contamination Reduction
应用背景This paper considers the problem of interference mitigation in multi-cell multi-antenna time division duplex (TDD) wireless systems for downlink transmission. An efficient way to obtain channel state information (CSI) at the base station is by using uplink pilots and reciprocity of the downlink channel.
At the same time, it has been shown that pilots from different cells contaminate each other, resulting in corruption of precoding matrices used by base stations, and high inter-cell interference. This paper studies the effects of shifting the location of pilots in time frames used in neighboring cells, and its effectiveness in obtaining better channel estimates, and, thereby, inter-cell
interference reduction.关键技术Wireless cellular network designs with multiple antennas have been adopted by several modern wireless systems, which aim for high throughput as well as high

一维稳态导热第二类边界条件的TDMA解法
一根长6cm的金属棒（下面的数据大致为金属铝的数据）水平放置，从左侧端面施加q=10w/(cm)2的热流，右侧端面的对流换热系数h=1000w/(m*m*k)，Tf=20摄氏度，导热系数可以选取lamada=200w/(m*k)。求稳态时各点温度。
采用TDMA算法求解线性方程组。
