QAM

a start book for programming in java tcl for network simulation

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)

信号与系统基础练习，演示了数字信号处理中常用的傅里叶变换，分析时域和频域的信息(Signals and systems based practice, demonstration of digital signal processing used in the Fourier transform of the time domain and frequency domain information analysis)

QAM,PSK,DPSK,FSK,MSK调制仿真，包括眼图输出，误码率输出，星座图，频谱，及实际wav文件的调制解调(QAM, PSK, DPSK, FSK, MSK modulation simulation, including eye diagram output, the output BER, constellation, spectrum, and actual modem wav files)

很好的风速模型，对风力发电的出力进行研究有很大帮助。(Good wind model, the output of wind power research helps a lot.)
