双态多址信道容量域的新界

New Bounds for the Capacity Region of the Finite-State Multiple Access Channel

Haim H. Permuter, Tsachy Weissman, Jun Chen

摘要:

考虑了反馈信道输出样本为任意时不变函数的变状态多址接入信道(FS-MAC)的容量域。我们为这个区域提供了一系列的内边界和外边界。这些界限是一致的,因此产生的能力区域,FS-MAC的状态过程是平稳的,遍历的,不受输入,和不可分解的FS-MAC反馈时,不允许。虽然容量区域一般是“多字母”的,但当应用于特定的感兴趣场景时,我们的结果会得出明确的结论。

英文摘要:

The capacity region of the Finite-State Multiple Access Channel (FS-MAC) with feedback that may be an arbitrary time-invariant function of the channel output samples is considered. We provided a sequence of inner and outer bounds for this region. These bounds are shown to coincide, and hence yield the capacity region, of FS-MACs where the state process is stationary and ergodic and not affected by the inputs, and for indecomposable FS-MAC when feedback is not allowed. Though the capacity region is `multi-letter' in general, our results yield explicit conclusions when applied to specific scenarios of interest.
