Asymptotic Performance of Linear Receivers in MIMO Fading Channels
K. Raj Kumar, G. Caire, A. L. Moustakas
Linear receivers are an attractive low-complexity alternative to optimal processing for multi-antenna MIMO communications. In this paper we characterize the information-theoretic p…

Space-Time Codes from Structured Lattices
K. Raj Kumar, Giuseppe Caire
We present constructions of Space-Time (ST) codes based on lattice coset coding. First, we focus on ST code constructions for the short block-length case, i.e., when the block-leng…

Coding and Decoding for the Dynamic Decode and Forward Relay Protocol
K. Raj Kumar, Giuseppe Caire
We study the Dynamic Decode and Forward (DDF) protocol for a single half-duplex relay, single-antenna channel with quasi-static fading. The DDF protocol is well-known and has been…
