matlab的图像滤波算法中的平均滤波算法源代码(image filtering algorithm matlab)

1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。 2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是 加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数 trellis来生成自己的相关参数。 3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打 孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。 4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)

dct precoded SLM method for PAPR reduction High Peak to Average Power Ratio (PAPR) is still a most important challenge in Orthogonal Frequency Division Multiplexing (OFDM) system. In this paper, we propose a Discrete Cosine Transform (DCT) precoding based SLM technique for PAPR reduction in OFDM systems. This technique is based on precoding the constellation symbols with DCT precoder after the multiplication of phase rotation factor and before the Inverse Fast Fourier Transform (IFFT) in SLM-OFDM System.
