Limited Feedback Precoder Design for Spatially Correlated MIMO Channels
Abstract— It is well-known that perfect channel state information (CSI) at the transmitter and the receiver (CSIT/CSIR) can be used to decompose a multi-antenna channel into a ba...

Non-Linear Precoding for OFDM Systems in Spatially-Correlated Frequency-Selective Fading MIMO Channels
— This paper presents non-linear precoding design in closed-loop multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) over spatiallycorrelated,...

Pseudo-signatures, Broadcast, and Multi-party Computation from Correlated Randomness
Unconditionally secure multi-party computations in general, and broadcast in particular, are impossible if any third of the players can be actively corrupted and if no additional i...

Lifetime optimization for wireless sensor networks with correlated data gathering
—The nodes in wireless sensor networks often collect correlated measurements. Not taking into account this information redundancy is detrimental to the network lifetime, since co...

Distributed Video Coding with Spatial Correlation Exploited Only at the Decoder
—A new pixel-domain Distributed Video Coding (DVC) scheme is proposed in this paper, in which both the temporal and the spatial correlations are exploited only at the decoder. A ...
