一个用于波音飞机的程序，还有相关文档，共相关人员参考(A program for Boeing aircraft, and related documents, a total of reference for the related personnel )

在OFDM仿真模型的基础上用MATLAB语言编写出OFDM发送、信道及接收整个系统,在系统仿真正确的前提下,对循环前缀、信道估计等性能改善方法进行进一步仿真验证 (In OFDM simulation model based on the use of MATLAB language to send the OFDM, channel and receive the entire system, in the system under the premise of the correct simulation of the cyclic prefix, channel estimation methods for further performance improvement simulation)

1st FIR filter is given and wee need to find 2nd FIR filter that meet magnitude complementary criterion. fminsearch is used for error minimization.

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.)

产生噪声调频干扰信号，并画出它的时域和功率谱(Generate noise FM jamming signal, and draw it in time domain and power spectrum)

设计低通滤波器对信号进行滤波，对比分析滤波前后信号的频谱；(Design of low pass filter for signal filtering, comparative analysis before and after filtering the signal spectrum )
