Description: 通信系统与仿真作业：
1）设计π/4-DPSK或16-QAM调制器仿真程序， 画出时域波形、 正交分量、同相分量波形，眼图，散点图等。
2）利用MATLAB进行DPSK在高斯信道下的BER性能仿真，并将结果与PSK性能进行比较。
3）已知 OFDM的数据传输速率为19.2Kbps， OFDM 符号长度为320，保护间隔为32点，子载波数为128，IFFT/FFT点数为256，载波频率320KHz，调制方案采用QPSK，仿真其在高斯信道下的BER性能。

Description: 这是一个 16-QAM 传输系统（ 或者说是基带等效传输系统） 包含发射机，信道和接收机的功能。 这个程序当中用到了发送滤波器，接收滤波器，均衡器等模块。作为一个基础的仿真，可以学习为如何通过 MATLAB 来仿真系统。(This is a 16-QAM transmission system (or baseband equivalent transmission system) that includes the transmitter, channel, and receiver functions. This program uses the transmit filter, receive filter, equalizer and other modules. As a basis for simulation, you can learn how to emulate the system through MATLAB.) Platform: |
