建立正交频分多路复用(OFDM)系统调制器的仿真模型，并编程给出具有K=10个子信道、符号区间T=100s、采用16点QAM信号时，OFDM系统调制器的输出信号。(The establishment of orthogonal frequency division multiplexing (OFDM) system, the simulation model of the modulator and the program is given with K = 10 Ge sub-channel, symbol interval T = 100s, with 16-point QAM signal, OFDM system, the modulator output signal .)

本程序是针对WCDMA，Rayleigh仿真进行的simulink仿真，附带很多个相关程序，还有关于信道仿真的问题的阐述，很好的！大家可以(this procedure is against WCDMA, Rayleigh simulation of Simulink simulation, many related ancillary procedures, Moreover, on the channel simulation of the elaborate and very good! We can look at)

用镜像矩阵求出矩阵的QR分解（正交三角分解），并求解线性方程组，该方法不必选主元，但其计算过程非常稳定。也可用于求矩阵的广义逆和求解线性最小二乘问题。子过程QRDCMP用镜像矩阵求m*n矩阵A的QR分解，A=Q^TR,其中Q是m*m正交矩阵，R为m*n上三角矩阵；子过程QRBKSB用矩阵的QR分解求解线性方程组Ax=b，其中A为n阶非奇异方阵。(Matrix obtained with the mirror matrix QR decomposition (orthogonal triangular decomposition), and solving linear equations, the method does not have to choose the main element, but its calculation process is very stable.
