LTE下行链路的仿真代码 基本模块都有 对系统仿真很有帮助(LTE downlink simulation code module has a helpful system simulation)

说明：  OFDM是将高速串行数据分成成百上千路并行数据,并分别对不同的载频进行调制,这种并行传输体制大大扩展了符号的脉冲宽度,提高了抗多径衰落的性能。同时,在传统的频分复用方法中,各子载波之间的频谱互不重叠,频谱利用率较低。而采用OFDM技术,一个OFDM符号之内包括多个经过调制的子载波的合成信号,每个子载波在频谱上相互重叠,这些频谱在整个符号周期内满足正交性,因而在接受端可以保证无失真恢复,从而大大提高频谱利用率。(OFDM divides high-speed serial data into hundreds of parallel data channels and modulates different carrier frequency separately. This parallel transmission system greatly expands the pulse width of symbols and improves the performance of anti-multipath fading. At the same time, in the traditional method of Frequency Division multiplexing, the spectrum between the sub-carriers does not overlap each other, the spectrum utilization ratio is low. In the case of OFDM, an OFDM symbol consists of multiple modulated sub-carriers, each of which overlaps in the spectrum, which is orthogonal throughout the symbol period, thus, no distortion recovery can be ensured at the receiving end, thus greatly improving the spectrum utilization ratio.)

产生随机共振现象的输入输出信噪比曲线，参数可以修改，不过过不要乱改动哦，不然振动不起来了。，已通过测试。 (SNR curve of the input and output of a stochastic resonance phenomenon, the parameters can be modified, too do not make changes Oh, or the vibration is not up. , Has been tested.)

雷达的恒虚警检测技术，二维cfar，采用十字形取数法(Radar CFAR detection technology, two-dimensional CFAR, using the cross number method)

基于双端电气量的故障测距，里面的输电线路是分布式输电线路，所以该模型已经考虑到了分布参数对测距的影响，能进行稳定而精确的测距！(Based on samples at both ends of the fault location, inside the transmission line is a distributed transmission line, so that the model has taken into account the effect of the distribution parameters ranging, enabling stable and accurate distance!)

说明：  目标跟踪问题的应用背景是雷达数据处理，即雷达在搜索到目标并记录目标的位置数据，对测量到的目标位置数据（称为点迹）进行处理，自动形成航迹，并对目标在下一时 刻的位置进行预测。本文简要讨论了用Kalman滤波方法对单个目标航迹进行预测，并借助于Matlab仿真工具，对实验的效果进行评估。 (kalman filter)
