这是文章Multiple Image Watermarking using the SILE Approach的matlab实现，可供研究该文的读者参考。(Multiple Image Watermarking using the SILE Approach)

LDPC译码算法，采用LOG方法，减少计算复杂度(LDPC decoding algorithm used LOG, to reduce the computational complexity)

这是关于mathlab软件使用的一些入门级教程，对mathlab初学者有一定的帮助。(This is an entry-level course about the using of mathlab , it may have some help for mathlab beginners .)

AN IMPORTANT class of theoretical and practical problems in communication and control is of a statistical nature.

我们将通过MATLAB仿真在发送平均功率和传输速率相同的情况下，在传输特性为理想的平的和非平(即存在码间干扰)的信道上，对多载波OFDM和单载波QPSK的误码率进行比较。(We will send the average power by MATLAB simulation and the transmission rate in the same circumstances, in the transmission characteristics of the ideal of peace and non-flat (as is the inter-symbol interference) of the channel, multi-carrier OFDM and single carrier QPSK BER rates were compared.)

搭建最小二乘法的三阶模型，采用该模型的输入输出数据进行参数辨识(The third-order model to build the least squares method, input and output data of the model parameter identification)

各种信号预处理方法 导数 平滑 傅里叶变换等等(Derivatives of various signal preprocessing method Fourier transform, and so smooth)

CDMA业务信道卷积编码实现，根据上下行信道区分生成不同码率的卷积码序列，original_sequence是原始输入序列，channel_select是信道选择参数，其中下行码率为1/2，上行信道为1/3 (CDMA business channel convolutional coding to achieve, according to the distinction between upper and lower line to generate a different channel bit rate of the convolutional code sequence, original_sequence is the original input sequence, channel_select is channel selection parameters, which downlink bit rate of 1/2, upstream channel for the 1/3)
