Matlab界面编程的一个实例， Matlab2008a(A example of MATLAB GUI program)

实验四 数字解调与眼图 1. 验证2DPSK 相干解调原理。 2. 验证2FSK 过零检测解调原理。 (Four digital demodulation experiment with eye diagrams 1. verify the 2DPSK coherent demodulation. 2. Verify 2FSK zero-crossing detection and demodulation principle.)

深度优先搜索属于图算法的一种,英文缩写为DFS即Depth First Search.其过程简要来说是对每一个可能的分支路径深入到不能再深入为止,而且每个节点只能访问一次.(DFS Depth First Search is a kind of graph algorithm, English abbreviation for DFS is the Depth First Search. The process is briefly branch of every possible path can t go deep into the deep, and each node can only access at a time.)

This is a superheterodyne reciever simulation, created in MATLAB - Simulink. The purpose is to study the effect of perturbations on the imaginary frequence and on the intermmediate frequence, in the context of incoherent demodulation.(This is a superheterodyne reciever simulation, created in MATLAB- Simulink.

Offset quadrature phase-shift keying (OQPSK) is a variant of phase-shift keying modulation using 4 different values of the phase to transmit. It is sometimes called Staggered quadrature phase-shift keying (SQPSK).

2017年0616，该频域分解（FDD）土木工程中的一个输出系统识别技术的流行，特别是在结构健康监测。作为一个输出的算法，它是有用的当输入数据是未知的。FDD是模态分析技术，生成系统的实现采用了频率响应（多）输出数据参考。所附的MATLAB代码实现了这一技术的模态参数识别。为了使用此代码，处理（趋势、过滤等）时间的历史数据必须存储在一个Excel文件（数据每一频道栏目）。检查“加速度。对于时间的历史文件的一个实例xlsx”。(In 2017, 0616, frequency domain decomposition (FDD), an output system in civil engineering, was popular in identification technology, especially in structural health monitoring. As an output of the algorithm, it is useful when the input data is unknown. FDD is a modal analysis technique, and the implementation of the system adopts a frequency response (multiple) output data reference.)
