MISO Broadcast Channel with Hybrid CSIT: Beyond Two Users
Sina Lashgari, Ravi Tandon, Salman Avestimehr
We study the impact of heterogeneity of channel-state-information available at the transmitters (CSIT) on the capacity of broadcast channels with a multiple-antenna transmitter and…
Bidirectional multi-pair network with a MIMO relay: Beamforming strategies and lack of duality
Aydin Sezgin, Holger Boche, Amir Salman Avestimehr
We address the problem of a multi-user relay network, where multiple single-antenna node pairs want to exchange information by using a multiple antenna relay node. Due to the half-…
Weighted Minimization for Sparse Recovery with Prior Information
M. Amin Khajehnejad, Weiyu Xu, Salman Avestimehr +1
In this paper we study the compressed sensing problem of recovering a sparse signal from a system of underdetermined linear equations when we have prior information about the proba…
