QPSK载波同步的实现程序，每一步有对应波形。(QPSK carrier synchronization procedures, every step of the corresponding waveform.)

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)

eemd,改进的emd程序，保证可用，识别频率阻尼比和模态(eemd, improved emd procedures to ensure that available to identify the frequency and modal damping ratio)

模型集成的模式看起来和他们各自的中心频率，这样的模式集体 复制输入的信号，而每个被顺利的经过成基带解调。在傅里叶域中，这对应 到以前的某个窄带。我们展示重要关系到维纳滤波去噪。事实上，提出的方法是一种推广 的经典维纳过滤到多个，自适应带区。我们模型分解为问题提供解决方案， 是从理论上也成立，还是很容易理解。变分模型有效的优化使用交替 方向法的乘数的办法。初步结果现有模式的吸引力表现 分解模型。尤其是，我们提出的模型是很多取样和噪音更健壮。最后，我们显示有前途 一系列的人工和实际实际分解结果数据。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
