本文给出了带反馈的离散时间非平稳高斯信道有限块长容量的一个上界。利用二次型极小化方法,证明了反馈容量C/sub n,FB/(P)和非反馈容量C/sub n/(P)满足C/sub n/(P)/spl les/C/sub n,FB/(P)/spl les/C/sub n/(P/sup */),其中P/sup */具体给定. >
We give an upper bound on the finite block length capacity of a discrete time nonstationary Gaussian channel with feedback. With the aid of minimization of a quadratic form, it is proved that the feedback capacity C/sub n,FB/(P) and the nonfeedback capacity C/sub n/(P) satisfy C/sub n/(P)/spl les/C/sub n,FB/(P)/spl les/C/sub n/(P/sup */) where P/sup */ is concretely given. >
