寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

Peak power ratio reduction in OFDM systems

在时间上使用隐式有限差分法，空间上使用后向差分法，对耦合波方程组离散化，进而对受激布里渊散射的能量反射率和产生SBS的阈值能量进行数值模拟。(Begin with the coupled wave equations which describe the interactions of the pump, the sound and the Stokes wave in the process of SBS. The equations are simplified according practical conditions, and one-dimension theoretical models are obtained aiming at unfocused pump as well as focused pump. The coupled equations are turned discrete using the method of implicit finite difference in terms of time and backward difference in terms of space.)
