在这篇文章中，我们考虑了允许差错的可变长度信源编码问题。分析了非渐近和渐近两种情况下码字长度的指数矩。结果表明，光滑Rényi熵表征了码字长度的最优指数矩。
In this paper, we consider the problem of variable-length source coding allowing errors. The exponential moment of the codeword length is analyzed in the non-asymptotic regime and in the asymptotic regime. Our results show that the smooth Rényi entropy characterizes the optimal exponential moment of the codeword length.
