OFDM 的全套程序， 包括调制， 解调， 误码， 眼图， 功率谱。。。(OFDM complete set of procedures, including modulation, demodulation, error, eye diagrams, power spectrum. . .)

使用误差累计的方式，来实时的更新背景，提取出最新的背景，(Cumulative manner using the error to the background of real-time update, extract the latest background)

现代通信系统matlab 第六章带限信道的传输的源代码(Transfer of modern communication systems matlab Chapter VI band-limited channel source code)

the name should less 40 bytes long and should be matlab tamala

this is mandelbrot fractal matlab code

该程序源代码实现了OFDM通信系统性能的仿真，调制方式有BPSK,QPSK,MSK,QAM,信道为AWGN和Rayleigh信道，并对有插入导频的符合IEEE802.11a的OFDM系统进行了仿真。(The program source code to achieve the performance of OFDM communication system simulation, modulation has BPSK, QPSK, MSK, QAM, for the AWGN channel and Rayleigh channel, and have inserted the line with the IEEE802.11a pilot of OFDM system simulation.)

说明：  图像的置乱加密和解密算法，需要输入加密密钥进行加密，然后只能输入相同的解密密钥才能得到原图像(Image scrambling encryption and decryption algorithms, need to enter the encryption key to encrypt, then enter the same decryption key only to get the original image)
