Information Bottleneck for a Rayleigh Fading MIMO Channel with an Oblivious Relay
Hao Xu, Tianyu Yang, Giuseppe Caire +1
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to op…

Information Bottleneck for an Oblivious Relay with Channel State Information: the Vector Case
Hao Xu, Tianyu Yang, Giuseppe Caire +1
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel. Due to the bottleneck constraint, it is impossible for…
