MIMO_OFDM联合仿真的matlab 源程序（很完整）

说明：  GE Fanuc LM9030 Software

说明：  对ofdm不同cp长度下系统性能的分析(Performance analysis of OFDM systems with different CP lengths)

用于手机模组中显示屏上，用来点屏的初始化代码(On the display module for mobile phones used to point screen initialization code)

说明：  数字信号的调制识别，提取了信号的时域特征与频域特征。包含神经网络训练。(Modulation recognition of digital signal.The time-domain and frequency-domain features of the signal are extracted. Including neural network training.)

CONVERT A MATRIX TO LOWER TRIANGULAR MATRIX

说明：  单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。(Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into a narrow-band spectrum spectrum. Digital Drive 20, changes in frequency from 0-2HZ uniform random samples.)
