对 2PSK 和 QPSK 通信信号的干扰仿真摘要：在通信信号干扰的设计试验过程中，通信信号干扰的仿真设计具有灵活性好、经济等优点，为对通信信号的干扰讨论工作带来了很大的便利。本文以 MATLBA 为实现工具，*****（做了什么），****（结论）。本通信干扰系统主要针对二进制相移键控、正交相移键控这两种通信信号的调制解调进行了干扰仿真和建模。实现了两种信号的时域和频域图形的绘制，以及在各种噪声干扰情况下的误码率分析。根据仿真过程中的数据信息，分析了不同调制样式和不同噪声大小以及调制解调过程中各种参数对通信信号性能的影响。完成两种信号的通信建模计算，得到调制和解调过程中的时域波形和频谱，直观显示出各种参数对通信的影响。主要设计一个通信平台，能模拟这两种通信信号的调制和解调，实现在平台上进行参数的输入和输出等交互功能。。关键词：二进制相移键控； 正交相移键控； 调制； 解调； 仿真； MATLAB； 误码率The interference of simulation and implementation of 2PSK and QPSK communication signalsAbstract：In the design and test of the communication signal interference,simulation of communication signal interference have many advantages,such as good flexibilities, economy e.g. and it takes great convenience to the research of communication signal interference.This communication jamming system is mainly with simulation and modelling to mo- dulation and demodulation of two kinds of signals:2PSK,QPSK. It realizes graphics protr- action of time and frequency domain,and BER(Bit Error Rate) analysis in various noise circumstance.According to the simulation process data information,we analyzed the effects of different modulation pattern, noise level and modulating parameters to communication.Complete two signal communication model calculation, to get the time domain waveform and spectrum in modulation and demodulation process.through these,it's convenient to vis- ual display the effects of parameters to modulation modes.Design a communication plat- form,simulating mod...
