发送端具有非因果信道状态信息的多用户信道容量界

Capacity Bounds for Multiuser Channels with Non-Causal Channel State Information at the Transmitters

Reza K. Farsani, Farokh Marvasti

摘要:

在本文中,容量的内和外边界建立的多用户信道与信道状态信息(CSI)已知的非因果关系在发射机:多址信道(MAC),广播信道(BC)与公共信息,和中继信道(RC)。对于每个信道,在一些特殊情况下,实际容量区域也被导出。具体而言,它示出,对于一些确定性模型与非因果CSI在发射机,类似于科斯塔的高斯信道,CSI的可用性在确定性接收机不影响容量区域。

英文摘要:

In this paper, capacity inner and outer bounds are established for the multiuser channels with Channel State Information (CSI) known non-causally at the transmitters: The Multiple Access Channel (MAC), the Broadcast Channel (BC) with common information, and the Relay Channel (RC). For each channel, the actual capacity region is also derived in some special cases. Specifically, it is shown that for some deterministic models with non-causal CSI at the transmitters, similar to Costa's Gaussian channel, the availability of CSI at the deterministic receivers does not affect the capacity region.
