基于反向试验信道的信息率失真函数计算方法

A calculation method of the rate distortion function based on reverse test channel

利用Lagrange乘数法和互信息与熵的关系,提出了一种基于反向试验信道的信息率失真函数计算方法,给出了信息率失真函数的参量表示式,分析了该参量表示式中参数的物理意义,并举例说明了其具体应用.

Using the Lagrange multiplier method and the relationship of mutual information and entropy, this paper gives the parametric representation of calculating rate distortion function based on reverse test channel and analysis the meaning of the parameter. And gives an example of application.
