ofdm/oqam系统源码 4qam调制下oqam与cp——ofdm比较(ofdm/oqam system source code modulation oqam 4qam with cp- ofdm Compare)

正交频分复用系统中信号的调制与解调，我们用傅里叶反变换和变换来实现(Orthogonal frequency division multiplexing system signal modulation and demodulation, and we use the inverse Fourier transform to achieve transform)

this algorithm is another self organizing maps

说明：  matlab版GPS卫星模拟器。给出了详细的设计说明，有很多简化和不完善的地方，旨在抛砖引玉！(Matlab version of the GPS satellite simulator. Given the detailed design specifications, and to simplify a lot of imperfections, and to congregate!)

16QAM调制信号的GAD定时恢复，对定时恢复环路的验证和实现(Gardner Timing Recovery for 16QAM)

目标跟踪，程序利用卡尔曼滤波器对对圆周运动的目标进行跟踪。绘制出期望信号、观测信号和滤波后点目标的运动轨迹。(Target tracking, the program the use of Kalman filter, right, right circular motion of the target being tracked. Draw out the desired signal, observation point target signal and the filtered trajectories.)

绘制瀑布图通过matlab语言，绘制转子个频率点个时间点的幅值变化情况(Draw waterfall figure)

中间位置算法，算术平均值算法，最小熵反褶积最好去去噪算法。(The algorithm of median location, arithmetic mean algorithm and minimum entropy deconvolution are the best denoising algorithms.)

说明：  实现QPSK位同步G算法，方法很经典，可以查看小数u和误差变化(Gardner matlab The QPSK bit synchronization g algorithm is implemented. The method is very classical, and the decimal u and error change can be viewed)
