离散时间无记忆高斯信源的失真率函数
在信息处理过程中,由于种种干扰因素的存在,不可避免地要丢失信息,产生失真.对于给定的信源,总是希望它的信息经过处理后所产生的平均失真在一定允许限度内的情况下,使得信源传输的信息率尽可能的小1].在数学上,即为在失真受约束条件下寻找传输信源信息传输率的最小值.这个最小值就是率失真函数R(D).
Distortion rate function of discrete time memoryless Gaussian source
In the process of information processing, due to the existence of various interference factors, it is inevitable to lose information and produce distortion. For a given source, we always hope that the average distortion of its information after processing is within a certain allowable limit, so that the information rate transmitted by the source is as small as possible, It is to find the minimum value of the transmission rate of the source information under the condition of distortion constraint. This minimum value is the rate distortion function R (d) (2021-04-05, matlab, 5KB, 下载0次)
