Channel State Prediction, Feedback and Scheduling for a Multiuser MIMO-OFDM Downlink
Hooman Shirani-Mehr, Daniel N. Liu, Giuseppe Caire
We consider the downlink of a MIMO-OFDM wireless systems where the base-station (BS) has M antennas and serves K single-antenna user terminals (UT) with K larger than or equal to M…
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…
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,…
Joint Source Channel Coding with Side Information Using Hybrid Digital Analog Codes
Makesh Pravin Wilson, Krishna Narayanan, Giuseppe Caire
We study the joint source channel coding problem of transmitting an analog source over a Gaussian channel in two cases - (i) the presence of interference known only to the transmit…
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…
