源码 qpsk仿真
利用randi函数产生10000个0、1随机数，对原信号signal进行分类每两个相邻随机数作为新信息SIGNAL并进行判断，若为0，则生成调制信息1+i，若为1，则生成调制信息-1+i，若为2，则生成调制信息-1-i，若为3，则生成调制信息1-i，从而实现QPSK调制

技术资料 Understanding_the_Basics_of_MIMO
An acronym for Multiple-In, Multiple-Out, MIMO communication sends the same data as several signals
simultaneously through multiple antennas, while still utilizing a single radio channel. This is a form of
antenna diversity, which uses multiple antennas to improve signal quality and strength of an R ...

matlab例程 A fast customizable function for locating and measuring the peaks in noisy time-series signals. Adju
A fast customizable function for locating and measuring the peaks in noisy time-series signals. Adjustable parameters allow discrimination of "real" signal peaks from noise and background. Determines the position, height, and width of each peak by least-squares curve-fitting.
matlab例程 Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular ban
Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communica ...

模拟电子 相敏检波电路鉴相特性的仿真研究
分析了调幅信号和载波信号之间的相位差与调制信号的极性的对应关系,得出了相敏检波电路输出电压的极性与调制信号的极性有对应关系的结论。为了验证相敏检波电路的这一特性,给出3 个电路方案,分别选用理想元件和实际元件,采用Multisim 对其进行仿真实验,直观形象地演示了相敏检波电路的鉴相特性,是传统的实际操作实验所不可 ...
