分布式网络，考虑拜占庭攻击，通过门限设计改善网络性能，提高分布式定位精确度(Distributed network, consider the Byzantine attack, by improving the design of network performance threshold, distributed improve positioning accuracy)

GPS 单系统单频伪距静态 单点定位 CEP95 2.9(Single point positioning)

一般时与儒略时以及GPS周、秒的相互转换(Conversion between general time and Julian time and GPS cycles and seconds)

说明：  水平集（level set）中快进算法（fast marching）算法的matlab工具箱，内容很全面。(Level Set (level set), Fast Forward algorithm (fast marching) algorithm m atlab Toolbox, which is very comprehensive.)

两个画蜂窝系统的程序。第一个画出六边形蜂窝图。以（0，0）点为中心(Two paintings cellular system. The first draw hexagonal honeycomb Fig. To (0,0) point as the center)

Massive MIMO n radio, multiple-input and multiple-output, or MIMO (commonly pronounced my-moh or me-moh), is the use of multiple antennas at both the transmitter

数字调制-OFDM-QPSK-峰均比-资料,很好很详细，学习ofdm很好的资料(Digital Modulation-OFDM-QPSK-PAR- information, very very detailed, very good information to learn ofdm)

说明：  matlab读取dat文件，带字符的那种，用于读取dat并把数据分开，(Matlab reads the dat file)

假设地下一倾斜界面，地层倾角为15°，地层是均匀的各向同性介质，地震波纵波传播速度为1500m/s，炮检距为0~500m，现绘制出折射波、直达波、反射波的时距曲线图(If the underground inclined interface, dip angle is 15 degrees, the formation is a uniform isotropic medium, seismic wave propagation velocity is 1500m/s, the offset is 0~500m, we draw the refraction wave, direct wave, reflected wave time distance curve)

matlab三维旋转。绕XYZ轴旋转的程序代码。(matlab three-dimensional rotation. Around the XYZ axis of the program code.)
