qfsk
- Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to ca

QPSK代码
- 正交相移键控（Quadrature Phase Shift Keyin，QPSK）是一种数字调制方式。它分为绝对相移和相对相移两种。由于绝对相移方式存在相位模糊问题，所以在实际中主要采用相对移相方式DQPSK。目前已经广泛应用于无线通信中，成为现代通信中一种十分重要的调制解调方式。(Quadrature phase shift keying (quadrature phase shift keyin, QPSK) is a digita

Digital Modulation Techniques Basic Concepts
- The phase of the output signal gets shifted depending upon the input. These are mainly of two types, namely Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK), according to the number of phase shif

计算机通信仿真课程设计
- BPSK与模拟通信系统相比，数字调制和解调同样是通过某种；在大多数情况下，数字调制是利用数字信号的离散值去；三种数字调制方式在抗干扰噪声能力和信号频谱利用率；2BPSK调制原理；二进制相移键控（BPSK）是利用基于MATLAB中的BPSK误码性能研究； MATLAB提供了卷积码的convenc和相应的Viterbi译码函数vitdec，可以快速地得到编译码的结果。(BPSK compared with the analog commu
基于MATLAB的MSK调制解调实现
- 利用MATLAB集成环境下的M文件，编写程序来实现MSK的调制解调，并绘制出解调前后的时域和频域波形及叠加噪声时解调前后的时频波形，根据运行结果和波形来分析该解调过程的正确性及信道对信号传输的影响。通过这次课程设计进一步加深了我对最小二进制相移键控（MSK）调制解调性能的理解与掌握，同时将课堂上学到的理论知识用于实践。增强了我在模拟仿真方面的能力，为以后系统开发和通信系统仿真打下了良好的基础。(The use of MATLAB in
