shift register code and pn sequence code

智能天线设计资料，请多多指教，是关于TDSCDMA系统的，希望对您有帮助！(smart antenna)

说明：  一个用matlab作时频分析的代码，大家可以看看他的分析方式(using Matlab for a time-frequency analysis of the code, we can look at his methods of analysis)

说明：  灰度变16进制包含了多种功能是各种代码中必要的一步(Grayscale variable hexadecimal system contains many functions, which is a necessary step in various codes.)

DESIGN and IMPLEMENTATION of a SHUNT ACTIVE POWER FILTER with REDUCED DC LINK VOLTAGE

ETF统计套利的书籍，目前正在用matlab进行回测，希望有喜欢的人，也可以了解下(ETF statistical arbitrage books, is currently in use of matlab to test, hope to have of the person you like, also can understand)

这是根据韩京清的自抗扰控制技术书本编写的ADRC仿真程序，运用到坦克炮控系统上(This is according to Han Jingqing the ADRC ADRC technical books written simulation program, applied to the tank gun control system)

说明：  利用Matlab编写求取4级移位寄存器的M序列 设初始序列为:1 1 1 1 通过一个四级的移位寄存器,其中在第三级有负反馈(一个模二加法),即将序列的第三位和第四位相加(如序列1 1 1 1经移位寄存器第一次移位后为0 1 1 1)的值再赋到第一位. 序列的周期为16.(The use of Matlab to prepare to strike four of the M shift register sequence based initial sequence as follows: 1 1 1 1 4 through a shift register, which in the third grade there is negative feedback (one-mode two adder), the upcoming series third and fourth combined (such as the sequence 1 1 1 1 by the shift register after the first shift for the 0 1 1 1) the value given to the first again. The cycle sequence was 16.)

说明：  一种改进的BP算法 MAtlab运用于预测(An improved BP algorithm is applied to predict MAtlab)
