　?　　bpsk信号的产生可用与仿真的输入信号(? Bpsk signals generated can be used with simulation of the input signal)

说明：  采用QAM调制的方式，实现OFDM信号的PAPR的降低，并且提供了由optisystem转换到MATLAB接口的代码(QAM modulation is adopted to reduce the PAPR of OFDM signal, and the optisystem port is provided to convert to MATLAB code)

QPSK调制解调函数 MatlaB自编函数(QPSK modulation and demodulation functions)

从实际应用的角度出发，提出利用跟踪微分滤波器抑制机冀挠曲变形产生的影响，通过杆臂效应补偿消 除干扰加速度，用延时补偿算法减少由数据传输延迟造成的量测信息误差。在此基础之上，采用“速度+姿态” 匹配方案，研究了基于H_滤波估计的快速传递对准方法.大量数值仿真、静态试验、动态跑车试验表明，这 些方法有收敛速度较快、精度较高的特点，并t,有较强的抗干扰能力。试验也验证了传递对准方法的有效、可 行，能满足控制系统对导航信息的精度要求. ()

自己需要给出坐标，GPS测距。主要是实现了基于maltab测距GPS测距原理(you should give coordinates, GPS ranging)

MATLAB代码，产生GNSS导航信号BOC调制的相关频谱特性(The generate of BOC signal AND ITS PDF)

The future satellite communication systems are re- quired to support the higher transmission data rate for providing the multimedia services by employing the e铿僣ient modulation method such as multi-level QAM.

说明：  eetop.cn_PLLnoise+jitter_ams model

基于MATLAB平台的通信系统的仿真，RS编码，OFDM调制，加入PLC信道噪声，并进行误码率的检测，运行无误，程序完整。(MATLAB-based communications system simulation platform, RS coding, OFDM modulation, adding PLC channel noise, and make BER testing, run correctly, the program integrity.)
