GPS多径抑制算法
根据多径信号的特点以及对导航定位精度的影响，利用一种能有效解决非线性非高斯问题的滤波算法－粒子滤波来估计多径信号
的时延参数。
针对传统的粒子滤波存在的粒子退化和贫化现象，将遗传算法嵌入到基本的粒子滤波框架的重采样步骤中，对其粒子滤波进行改进，既解决了粒子退化现象，也保持了粒子空间的多样性。
对于多径信号幅度的估计，利用了解决线性问题的最优估计－卡尔曼滤波。

massive mimo Fundamentals, Opportunities and Challenges
应用背景Massive multiuser MIMO (MISO):
◮ M ≫ K ≫ 1 (think 100 × 10 or 500 × 50)
◮ coherent, but simple, processing
◮ Potential to dramatically improve rate & reliability
◮ Potential to drastically scale down TX power
◮ Not only theory, at least one known testbed (64× ∼10)
关键技术
Massive MIMO Operation
Not enough resources for pilots & CSI feedback, so operate in TDD.
◮ On the uplink,
◮ acquire CSI from uplink pilots and/or blindly from data
◮ detect symbols
◮ M ≫ K ⇒ linear processing (MRC, ZF, MMSE) nearly optimal
◮ On the downlink,
◮ use CSI obtained on the uplink
◮ make necessary adjustments based on reciprocity calibration
◮ apply multiuser MIMO precoding
◮ simple precoders desirable (and very good!): MRT, ZF, MMSE, ...
◮ MRC/MRT operation
◮ intracell interference will appear as

超像素图像SLIC算法
SLIC算法是一种小范围的像素迭代形成超像素的算法，与K-means算法有相似之处，不过SLIC在找最近邻居时不需要搜索整个空间，从S*S中就可以得到很好的结果。在VS2008，MFC实现。

A program to demonstrate the optimization process of particle swarm optimization. A two-dimensional objective function is visualized by level of grey: the lighter the color, the higher the function value. The particles are shown as red circles, their trajectory as red lines.-A program to demonstrate the optimization process of particle swarm optimization.
