论文摘要
本文认为原始的高斯钻石通道的分布式信息瓶颈(D-IB)问题,带有两个继电器和瑞利褪色。由于瓶颈的约束,无力不可能在每个实现中告知完美频道状态信息(CSI)的目标节点。为了评估瓶颈速率,我们通过假设目的地节点知道CSI和继电器可以彼此合作,提供了上限,以及三个具有简单符号的逐个符号继电器处理和压缩的可实现的方案。数值结果表明,所提出的可实现方案获得的下限可以接近上限,在广泛的相关系统参数上。
This paper considers the distributed information bottleneck (D-IB) problem for a primitive Gaussian diamond channel with two relays and Rayleigh fading. Due to the bottleneck constraint, it is impossible for the relays to inform the destination node of the perfect channel state information (CSI) in each realization. To evaluate the bottleneck rate, we provide an upper bound by assuming that the destination node knows the CSI and the relays can cooperate with each other, and also three achievable schemes with simple symbol-by-symbol relay processing and compression. Numerical results show that the lower bounds obtained by the proposed achievable schemes can come close to the upper bound on a wide range of relevant system parameters.
