OPNET14.5的帮助文档，几乎所有的现行阶段的教材都是由该软件帮助文档改编或缩减而成，所以该文档为OPNET学习者必备手册之一。(OPNET14.5 the help of documents, almost all of the current phase of the teaching materials are adapted to the software help files or reduced form, so the document must have the manual for one of OPNET learners.)

实现了QPSK的调制，使用了ise自带的dds的IP核(QPSK is modulated and the IP core of DDS is used in ise.)

HDLC控制协议中CRC校验码算法代码，为CRC16，Verilog语言(HDLC Control Protocol Code in the CRC checksum algorithm code for CRC16, Verilog language)

四路信号的多路复用研究及仿真实现，通过时隙的分配观察复用前后的波形图。(Four channel signal multiplexing research and simulation implementation, through the slot allocation to observe the waveform before and after multiplexing)

用的Rsoft软件 模拟了两个矩形直波导的耦合情况，并监测其功率变化。 可用于分析微环耦合区域的光场。(Rsoft software used to simulate the two rectangular straight waveguide coupling, and to monitor their power change. Can be used to analyze micro-ring coupling region of the light field.)

ADMM算法 切普信号的参数估计问题 包括个数估计和频率估计(The parameter estimation of Chep signal based on ADMM algorithm includes number estimation and frequency estimation.)

实现sc-fde的信道估计和频域均衡，通信专业必备，MATLAB软件(Implementation of channel estimation and frequency domain equalization SC-FDE)

说明：  最大限度地平 FIR 逼近 （拉格朗日插值法） 拉格朗日插值是一种时域方法，导致基于多项式的筛选器的一个特殊情况。用 M 次多项式近似表示输出信号。最简单的情况 (M = 1) 对应于线性插值。让我们设计和分析将通过各种馏分拆分单元延迟的几种线性分数时滞滤波器：(Maximally-Flat FIR Approximation (Lagrange Interpolation) Lagrange interpolation is a time-domain approach that leads to a special case of polynomial-based filters. The output signal is approximated with a polynomial of degree M. The simplest case (M=1) corresponds to linear interpolation. Let's design and analyze several linear fractional delay filters that will split the unit delay by various fractions:)
