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…
Channel State Feedback Schemes for Multiuser MIMO-OFDM Downlink
Hooman Shirani-Mehr, Giuseppe Caire
Channel state feedback schemes for the MIMO broadcast downlink have been widely studied in the frequency-flat case. This work focuses on the more relevant frequency selective case,…
Hard Fairness Versus Proportional Fairness in Wireless Communications: The Multiple-Cell Case
Daeyoung Park, Giuseppe Caire
We consider the uplink of a cellular communication system with users per cell and infinite base stations equally spaced on a line. The system is conventional, i.e., it does not…
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…
Bit-interleaved coded modulation in the wideband regime
Alfonso Martinez, Albert Guillen i Fabregas, Giuseppe Caire +1
The wideband regime of bit-interleaved coded modulation (BICM) in Gaussian channels is studied. The Taylor expansion of the coded modulation capacity for generic signal constellati…
A Practical Approach to Lossy Joint Source-Channel Coding
Maria Fresia, Giuseppe Caire
This work is devoted to practical joint source channel coding. Although the proposed approach has more general scope, for the sake of clarity we focus on a specific application exa…
