MUSIC算法MATLAB程序

运用matlab仿真实现多相滤波结构，带有中文注释，简单易懂。可以运行直接观察波形(Using MATLAB simulation to achieve polyphase filter structure, with Chinese annotation, easy to understand. Direct observation waveforms can be run)

加窗QPSK-OFDM调制解调，每个OFDM符号采用QPSK调制方式，并画出了时域对比图(Windowed QPSK-OFDM modulation and demodulation, each OFDM symbol using QPSK modulation and a time-domain comparison chart shown)

采用卡尔曼滤波器对系统的俯仰角、 滚转角和航向角的误差进行最优估计；设计数据融合的判别准则，并根据判据的判断结果调整卡尔曼 滤波器中的量测信息，使系统可用于小型无人机的定高自主飞行(Kalman filter system pitch angle, roll angle and yaw angle error optimal estimation design data fusion criterion, and adjust according to the criterion of judging the results of measurement in the Kalman filter, making the system set high for small UAVs autonomous flight)

说明：  频分复用信号的生成以及演示，与英文工具书匹配，很好用！(FDM signal generation)

说明：  太赫兹通信方面的代码，可以对照相关文献看(Terahertz communication)

OFDM系统，包括系统的编码，调制，转换，发送，时间同步，频率同步(OFDM systems, including system encoding, modulation, conversion, send, time synchronization, frequency synchronization)

说明：  1. 程序完成了BCH信道编码+BPSK调制解调技术在线性高斯白噪声环境下的通信仿真，并且绘制了多个编码格式下的误码率-比特信噪比（Eb/N0）仿真曲线 2. BPSKCode.m 主程序入口，运行该文件执行主程序(1.
