GApso2011 仿真与比较，matlab语言开发的，请大家使用！！(GApso2011 simulation and comparison, matlab language development, please use! !)

信道估计程序，ieee发表的文章对应的原码，本人已经验证，可以使用。(Channel estimation procedures, ieee post corresponding to the original code, I have verified that you can use.)

课程设计 作息时间控制 nimei miiii(Curriculum design schedule control nimei miiii)

C语言编写的傅立叶正逆变换，经过测试与matlab里面的.m算法结果一致。还有数据测试可用。适用于工程信号处理中。(C language of the Fourier transform, After test and Matlab inside m algorithm results. There are data test available. Suitable for engineering signal processing.)

matlab教程，好东西,希望大家喜欢,给我点鼓励(matlab tutorial, good stuff, hope you like, give me to encourage)

自适应KF对航行器进行滤波，包括sage_husa,和简化的自适应算法。(KF adaptive filtering for aircraft, including sage_husa, and simplified adaptive algorithm.)

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.)
