基于matlab语言的含有延时环节的不完全微分PID算法程序(Incomplete differential PID program)

说明：  基于神经网络算法的图片识别，卷积神经网络(Image recognition based on neural network algorithm)

聚类算法的简单介绍 感觉讲的蛮好的 上传来共享(Clustering algorithm briefly talked about feeling fine upload to share)

说明：  提出了正交频分复用(O FDM ) 系统中一种新的载波频偏估计算法L 载波频偏估计过程可分 为获取和跟踪, 其中, 获取过程和时间同步是同时完成的L新算法可实现的最大载波频偏获取范围 是整个信号带宽的一半L新的跟踪算法是一个最大似然算法, 在加性白噪声高斯信道(AW GN ) 下, 当N (训练序列长度的一半) 等于128 时, 其性能比Schm idl 算法提高约7127 dB 在多经信道下, 当 信噪比不是很高时, 新算法仍具有优势L(new carrier f requency offset est imat ion scheme in o rthogonal f requency division mu lt ip lex ing (O FDM ) system is p ropo sed.
