读取SAC格式天然地震数据，可以先读取158字节道头，并且输出NPTS（数字字母码格式），然后开始读取地震数据(Read SAC natural seismic data format that can be read 158 bytes road head, and the output NPTS (alphanumeric format), and then start reading the seismic data)

QPSK 调制全称 Quadrature Phase Shift Keying，意为正交相移键控，是 一种数字调制方式。它的频带利用率高，且抗干扰性能强，已经成为现代通信 技术中一种十分重要的调制解调方(QPSK’s full name is Quadrature Phaseshift Keying which is a kind of digital modulation types. It has been widely used in wireless communications and has become very important in modern communication because of its high bandwidth efficiency and strong anti-interference performance)
