无线通信抗衰落，合并器输出信噪比的概率密度函数比较。选择性合并，最大比率合并，等增益合并的概率比较(Slow Fading Plot Outage Probabiloty vs SNR for maximum ratio combining, coherent combining and antenna selection.)

主要对扩展卡尔曼滤波（EKF）、无迹卡尔曼滤波（UKF）及改进无迹卡尔曼滤波（MAUKF）算法进行研究，研究了三种算法的基本原理和各自的特点。其中扩展卡尔曼滤波器是将卡尔曼滤波器局部线性化，其算法简单，计算量小，适用于弱非线性、高斯环境。无迹卡尔曼滤波器是用一系列确定样本来逼近状态的后验概率密度。改进无迹卡尔曼滤波算法在UKF的基础上引入衰减因子。(Improved Kalman filtering algorithm)

64QAM基带系统接收机matlab代码：添加AWGN噪声，进行接收端匹配滤波器，8倍下采样，解调信号。(64QAM baseband system receiver matlab code: add AWGN noise, matched filter receiving end, eight times the down-sampling, the demodulated signal.)

MATLAB Coder™ generates standalone C and C++ code from MATLAB ® code. The generated source code is portable and readable. MATLAB Coder supports a subset of core MATLAB language features, including program control constructs, functions, and matrix operations. It can generate MEX functions that let you accelerate computationally intensive portions of MATLAB code and verify the behavior of the generated code.
