FFT 的C语言实现
应用背景快速傅里叶变换 (fast Fourier transform), 即利用计算机计算离散傅里叶变换（DFT)的高效、快速计算方法的统称，简称FFT。快速傅里叶变换是1965年由J.W.库利和T.W.图基提出的。采用这种算法能使计算机计算离散傅里叶变换所需要的乘法次数大为减少，特别是被变换的抽样点数N越多，FFT算法计算量的节省就越显著。
关键技术FFT的基本思想是把原始的N点序列，依次分解成一系列的短序列。充分利用DFT计算式中指数因子 所具有的对称性质和周期性质，进而求出这些短序列相应的DFT并进行适当组合，达到删除重复计算，减少乘法运算和简化结构的目的。

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
