this code simulate pure aloha .

是本科毕设的题目，实现六自由度运动学逆解算法，有详细的注释。( The title of the commercial is undergraduate course you Six degrees of freedom to achieve inverse kinematics algorithm, There are detailed notes.)

数字通信中的16QAM映射，采用格雷码编码，包括星座图的显示，简单明了清晰，由此可以退出64,128QAM的matlab编码(Digital communication 16QAM mapping, the use of Gray coding, including the constellation display, simple clear, it can be out of the 64,128 QAM matlab code)

针对数字卫星常用的 7 种通信信号调制方式(QPSK、8PSK、16QAM、32QAM、64QAM、16APSK、32APSK)，对零中心归一化瞬时幅度谱密度最大值、四次方谱、幅度、高阶累积量四种特征参数进行了分析，提出了一种联合特征参数的信号调制识别方法．(Aiming at seven communication signal modulation modes commonly used in digital satellite (QPSK, 8PSK, 16QAM, 32QAM, 64QAM, 16APSK and 32APSK), four characteristic parameters of zero-center normalized instantaneous amplitude spectral density, quadratic spectrum, amplitude and high-order cumulant are analyzed, and a signal modulation recognition method of joint characteristic parameters is proposed. Method.)

说明：  bch 编码、解码程序，可以对任意长度的信息添加纠错码。(BCH encoding, decoding procedures can be arbitrary length of the right information to add error-correcting codes.)
