基于MATLAB的支持向量机工具箱，好用(Support vector machine based on MATLAB toolbox, easy to use)

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

说明：  克里格法（Kriging，KRG）是由法国统计学家 Matheron 于 1963 年提出的，为纪念南非金矿工程师 Krige（Krige, 1951）曾于 1951 年使用回归方法对空间场进行预测的开创性研究，Matheron 将该方法命名为 Kriging，最开始该方法常被用于对矿产储量分布情况进行预（Matheron, 1963）。目前该方法作为最常用的空间插值算法，被广泛应用于地理科学、环境科学、大气科学等研究中。(Kriging (KRG) method was proposed by Matheron, a French statistician, in 1963. In order to commemorate the pioneering research of Krige (1951), a gold mine Engineer in South Africa, who used regression method to predict the spatial field in 1951, Matheron named this method Kriging. At first, this method was often used to predict the distribution of mineral reserves (Matheron, 1963) . At present, as the most commonly used spatial interpolation algorithm, this method is widely used in geographical science, environmental science, atmospheric science and other research.)

bpsk莱斯信道衰减simulink的仿真(bpsk_mp_rician_fading)

实上，我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体，看作一个级联码的编码器，同理，外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。 本次仿真外编码采用（7，4）HAMMING码，内编码采用（2，1，3）卷积码。交织编码采用（7，4）卷积交织编码或循环等差交织编码。除特别说明外，交织编码采用前者即（7，4）卷积交织编码。 (failed to translate)

谱系聚类发 给定聚类点数可得到聚类中心 很好很强大(Hierarchical clustering distributed clustering fixed points can be obtained very powerful cluster centers)

说明：  用simulink搭建的双馈风机模型，可用于风机并网的模拟，计算。较为复杂(Double-fed fanThe model of doubly-fed fan built by Simulink can be used to simulate and calculate the fan connected to the grid. More complex)

一个独立成分分析的测试文件，包含了几个声音文件，可以用来测试自己的盲信号分离算法。(An independent component analysis of the test file that contains a number of sound files that can be used to test their algorithm for blind signal separation.)
