MIMO Relay Network With Precoding [PDF]
IEEE Communications Letters, 2016 We study the achievable rate in a MIMO, dual-hop, relay network where source and relay nodes may precode their input signals before transmission. Although an iterative expression for optimal precoders in this scenario is available in the literature, the corresponding achievable rate cannot be obtained analytically.

Interference Mitigation for Cognitive Radio MIMO Systems Based on Practical Precoding
, 2011 In this paper, we propose two subspace-projection-based precoding schemes, namely, full-projection (FP)- and partial-projection (PP)-based precoding, for a cognitive radio multiple-input multiple-output (CR-MIMO) network to mitigate its interference to a

Spatially-coupled precoded rateless codes [PDF]
2013 IEEE International Symposium on Information Theory, 2013 Raptor codes are rateless codes that achieve the capacity on the binary erasure channels. However the maximum degree of optimal output degree distribution is unbounded. This leads to a computational complexity problem both at encoders and decoders.
