介绍Probability Generation Function的参考书，有用的数学工具。 研究随机过程，排队论的同学可以参考(Probability Generation Function useful mathematical tool. Stochastic processes, queuing theory)

本例用matlab语言实现了4QPSK的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(Matlab language used in this case achieved 4QPSK codec and channel through awgn simulation. Monte Carlo simulation method, the BER performance, drawing curves. Algorithm can be used for research or courses.)

说明：  一份初学MATLAB_gui者比较好的实例代码；来自《精通MATLAB GUI》，其中例子丰富实用，程序代码丰富。(A novice compared MATLAB_gui good examples of code from &quot proficient in MATLAB GUI&quot , in which the rich examples of practical, code-rich.)

基于四阶累积量的联合对角化，其中给出两种四阶累积量计算方法，方便理解。这个算法还是比较难的，可以参看下独立分量分析中的jade算法(Fourth-order cumulant-based joint diagonalization, which gives two fourth-order cumulant method, easy to understand. This algorithm is quite difficult, you can see under the jade independent component analysis algorithm)

几何活动轮廓的matlab程序，可用性强，写的很好。(Geometric active contour the matlab program, availability, and write well.)

BPSK MATLAB仿真程序。。。。。。。。。。。。不包括误码率计算(BPSK MATLAB simulation program............ Does not include bit error rate)

说明：  常规的单载波调制技术在带宽有限的测井电缆上的低传输速率制约着成像测井技术的发展。在分析测井 电缆传输特性和 OFDM 技术原理的基础上 ,设计了一种基于 OFDM 技术的测井电缆高速数据传输系统 ,并介绍了 基于 OFDM 技术的测井电缆高速数据传输系统的参数设计和工作原理 ,给出了不同长度测井电缆上的测试结果。 电缆实测结果表明 ,在 7 000 m长的测井电缆上 ,基于OFDM 技术的测井电缆高速数据传输系统可获得900 kbit / s 以上的数据传输速率和低于 5E28 的误码率。当变压器的接入模式为 Mode2II时 ,系统最高的数据传输速率可达到 1. 1 Mbit/ s。(To solve t he low data t ransmission rate problem in t he conventional single car rier mod2 ulation met hod for logging cable and enhance t he data t ransmission rate , a new data t ransmission system with high data t ransmission rate for logging cable is propo sed , which is based on t he Or2 t hogonal Frequency Division Multiplexing (OFDM) technology. The working principle of OFDM modem and t he procedure of data t ransmission system are al so presented and lot s of test s are car2 ried out on logging cables with different lengt hs. It is verified that t he data t ransmission rate can reach 900 kbit/s on 7 000 meter s logging cable wit h bit er ror rate (BER) lower t han 5E28 , and t he maximum data t ransmission rate is 1. 1 Mbit/s under Mode2II of t he t ransformer .)
