傅里叶变换

使用Devexpress开发的进销存系统源代码，建立了简洁明了的物品进销存流程管理。

用链表实现多项式的加减乘除以及多项式的打印显示(Addition, subtraction, multiplication, division and display of polynomials by linked list)

通过M atlab 模拟了随机产生的一定概率分布的信号序列, 叠加高斯噪声后利用最大后验概率(MAP)检 测到的误码率, 做出BER~ SNR曲线, 并与理论计算得到的曲线进行比较, 两者吻合.(M atlab simulated by a certain probability distribution of random signal sequence, use of superposition of Gaussian noise is the maximum a posteriori (MAP) detection to the error rate, making BER ~ SNR curves obtained with the theoretical curve of the combined fit.)

一个关于AT91SAM7SE的工程例子，部分代码为本人所写，主要为一个键盘处理的程序，程序需要在Keil下编译(A project on the AT91SAM7SE example, some code I wrote, mainly a keyboard handling procedures, the program needs to compile under Keil)

该程序为卫星定轨程序，主要用于对卫星的位置以及卫星速度进行计算 satellite orbits determination  //------------------------------------------------------------------------------ // // Exercise_2_6.cpp // // Purpose: // // Satellite Orbits - Models, Methods, and Applications // Exercise 2-6: Initial orbit determination // // Notes: // // This software is protected by national and international copyright. // Any unauthorized use, reproduction or modificaton is unlawful and // will be prosecuted.

让一个地址簿,包括ID、名称、 电话号码、地址和公司。 可以插入、显示、搜索和删除。(make an address book,include ID,Name, Phone number,Address and company number. can Insert,Display,Search and Delete.)

对数据进行聚类，方便进行下一步的计算，如20个数，分为四类，就会根据其数字特性按照最小二乘进行分类，并计算出质心-Clustering of the data to facilitate the next step of the calculation, such as the number 20 is divided into four categories according to their number of properties will be classified according to least squares and calculate the centroid
