在数字通信系统中,滤波器是其中重要部件之一, 滤波器特性的选择直接影响数字信号的恢复。在数字信号接收中, 滤波器的作用有两个方面,第一是使滤波器输出有用信号成分尽可能强;第二是抑制信号带外噪声,使滤波器输出噪声成分尽可能小,减小噪声对信号判决的影响。
(In digital communication system, the filter is one of the important components of the filter characteristics of the choice of a direct impact on digital signal recovery. In the digital signal receiver, the filter s role is twofold, first is to filter the output useful signal components strong as possible the second is the signal-band noise suppression, so that filter output noise components as small as possible, reducing the noise on the signal the impact of decision.)

C_PSO.m
粒子群算法,用于聚类.粒子群在迭代进行的过程中有可能出现早熟收敛
的问题而陷入局部最优解,因此文中在 PSO 算法部 分,设置两个变量对每个粒子和粒子群的状态进行实 时地监控,以便当检测到粒子或粒子群出现早熟收敛 现象时,能及时地对其进行变异操作,增加粒子的多样 性,使其跳出局部极值的束缚,在多维解空间中开始新 的搜索(C_PSO used for clustering)

Canny边缘检测算法
图像边缘是图像最基本的特征之一,是图像中灰度发生剧烈变化的像素点的集合,边缘检测效果将直接影响图像分析与识别。传统边缘检测算子对噪声较为敏感、边缘定位不够精确,使其在实际工程中应用较少。Canny于1986年提出Canny边缘检测算法,并获得了广泛应用。

超高速OFDM系统传输模型 CP
在研究了超高速OFDM系统传输模型的基础上,对OFDM系统的传输信号结构进行了分析,结合传统的多普勒频移算法,用OFDM信号循环前缀所包含的相对频偏信息设计了实时性较好的多普勒频移估计方法,并分析了多径效应对于循环前缀数据的“污染”效应,对该算法进行了优化,提高了算法的频移估计性能,并对该算法进行了性能验证。(Based on the study ultra-high-speed transmission of OFDM system model, the OFDM signal structure for the transmission system is analyzed, combined with traditional Doppler shift method, the relative deviation OFDM signal with cyclic prefix information contained in the real-time design Doppler shift better estimation methods, and analyzes the " pollution" effect of multipath effects for cyclic prefix data, the algorithm has been optimized to improve the frequency estimation algorithm performance and the performance of the algorithm verification.)
