编写卡尔曼滤波程序实现航迹的滤波估计，并计算出误差，仿真曲线(Kalman filter procedure to prepare implementation of the filtering track estimate and calculate the error, the simulation curve)

用MATLAB画一个弯曲的圆柱 思想：把圆柱按轴线分若干段，在每个断面画圆，圆的法线就轴线的切向方向。柱面画若干平行于轴线的线条，其中用到平行单位矢量点积等于1，不平行的结果是[-1，1）。 (MATLAB painting with a cylindrical curved thinking: the cylinder axis by a number of sub-paragraph in each section drawcircle, round on the normal axis of the tangential direction. Painted a number of cylindrical axis parallel to the lines, which use a parallel unit vector point plot equal to 1, the result is not parallel to [-1,1).)

NS 仿真软件输出结果的分析。有NAM 和 MONITOR输出结果的具体分析，希望对大家有用。(NS simulation software output analysis. MONITOR output with NAM and the specific analysis, we want to be useful.)

This paper studies a cooperative cognitive radio net-work where two primary users (PUs) exchange information with the help of a secondary user (SU) that is equipped with multiple antennas and in return, the SU superimposes its own messages along with the primary transmission. The fundamental problem in the considered network is the design of transmission strategies at the secondary node. It involves three basic elements: first, how to split the power for relaying the primary signals and fo

Active approach - TOA Inter(Active approach- TOA Inter)

matlab中simulink得自定义模块仿真必备(matlab to simulink simulation module must have custom)

说明：  在OFDM系统中，为了降低峰均功率比，采用SLM算法，该程序就是相应的Matlab源码(In OFDM system, in order to reduce the PAPR, SLM algorithm used, the program is the appropriate Matlab source)
